Homemade Ketchup and French Fries

The tomatoes were turning on me. A few weeks ago they were red and rosy, destined for a starring role in a BLT. Now, I'm not sure if they can withstand the scrutiny of the spotlight. They are still light years beyond what appears during the winter here in the Midwest, but not quite the ones you can slice up, sprinkle with salt, and eat raw. I kind of wish I would have known this before I bought a huge batch of them at the farmers market, but oh well. With way too many tomatoes, I realized it was time to cut my losses and make something that would last. And for some reason all I could think about was ketchup.

Ketchup seemed like the perfect way to use up leftover tomatoes. All I had to do was cook the toms down with some spices and bottle it up, right? But you don't eat ketchup with a spoon (at least I don't). It needed a partner, something to carry the flavor. It was only then that I questioned how much I actually use ketchup these days.

I mean, I think I've had the same monster bottle of Heinz ketchup in my fridge for months now. The condiment has taken a lot of flack recently. While it's been sacrilege to put ketchup on hot dog for a while now (in Chicago at least), the angry letters are coming in from all over the culinary map. Burgers are now off limits to some. Even fries at restaurants are starting to be sided with an array of other condiments, like aioli (which can be delicious). I even find myself slipping down the slope into anti-ketchup elitism.

But like most children that grew up in America, I have awfully found memories of dunking french fries in ketchup. I loved the way the cool condiment clashed with the hot fries. It may be an elementary pleasure, but it's a pleasure nonetheless. The problem is that some commerical ketchups mar the taste of whatever they touch. They are too sweet.  But what if I were able to make a ketchup that I wasn't embarrassed to have around? One that would latch on to fries and actually make them taste better?

The goal was to reaffirm my love of an old childhood classic, while hopefully updating it to my more balanced palate.

For help I checked out a whole slew of ketchup recipes. The history of ketchup is sketchy, and some modern cooks, like Heston Blumenthal, have followed the trail back to India and Asia. Their research turns up condiment that is loaded with things that never come anywhere near ketchup today. I think their pursuit is utterly fascinating, but it's a trip I didn't want to take. I wanted ketchup that was still familiar to me. It need to be loaded with tomatoes, slightly sweet, with a background laced with spices.

For that reason, I settled on a recipe by Hugh Fearnley-Whittingstall. He's the mastermind behind Britain's River Cottage, a series of TV shows and books. His enthusiasm for ketchup is infectious. He loves the condiment when it is made correctly, and has even hosted a ketchup cookoff on one of his shows. I also love that fact that he's particularly mum about his own recipe, going so far as say he'd never give it away. He'd like it to remain "a trade secret." There is, confusingly, a recipe for ketchup in the River Cottage Meat Book. Perhaps it is not his treasured recipe, but I figured it would be a good place to start.

It doesn't disappoint. The first taste is the burst of fresh tomato flavor, but the end is layered with the incredible bounty of spices which include mustard, cinnamon, allspice, cloves, mace, celery seeds, and black peppercorns. It's almost good enough to eat with a spoon.

Luckily, there were fries. I stumbled upon this recipe in eGullet a few months ago, and it has made fry making process an easy going affair. It utilizes the standard double-fry method, but with one trick. After the first fry the potatoes are drained and then left to cool in the fridge. This effectively drys out the crust of each potato. When they are fried again that crust turns extra crispy, leaving you with gloriously crunchy fries with creamy interiors. It's a great method.

The problem with frying has and will always be what to do with the epic amount of oil. It seems like a monumental waste to chuck it out after one use. But I don't like to think about it that way. Frying to me is an indulgence, a supreme act of gluttony that gets in the way of common sense. Because it is a expensive and wasteful, I tend to deep fry things only rarely. Now, each time I do decide to fry it becomes an event. I relish the times when I get to glug out the oil, because I know something like this awaits.

Homemade Tomato Ketchup

ketchupandfries 02
  • 6 pounds tomatoes, roughly chopped
  • 4 onions, sliced (I used a mixture of red and white)
  • 1 jalapeno pepper, stemmed, seeded, and chopped
  • 1/2 cup brown sugar
  • 3/4 cup cider vinegar
  • 1/4 teaspoon dry mustard
  • 1 cinnamon stick
  • 1 1/2 teaspoons whole allspice
  • 1 1/2 teaspoons whole cloves
  • 1 1/2 teaspoons ground mace
  • 1 1/2 teaspoons celery seeds
  • 1 1/2 teaspoons black peppercorns
  • 1 bay leaf
  • 1 garlic clove, peeled and bruised
  • cayenne
  • salt
ketchupandfries 04

Toss the tomatoes, onions, and jalapeno into a large pot. Turn the heat to medium cook until everything is soft. Stirring occasionaly, this should take about 20 minutes. Then take a ladle full at a time and push through a metal strainer. You want to keep the juice and discard any of the solids that stick to the strainer.

Pour the liquids back into the pot and add the sugar, vinegar, and mustard. Combine the cinnamon, allspice, cloves, mace, celery seeds, black peppercorns, bay leaf, and garlic in a bowl. Then wrap up the contents in some cheesecloth or transfer to an unused tea ball like I did.

Add it to the pot.

Bring mixture to a boil, then reduce to a simmer. Cook for about 40 to 60 minutes, or until the mixture has reduced to a ketchup like consistency. Taste occasionally. Remove the spice mixture if it seems like the ketchup is becoming to strong. Mine took about an hour, and after about 40 minutes I removed the spice mixture. When it's all done, season with salt to taste.

Let cool, and then transfer to a container. It should last for about a month.

Freshly Fried French Fries

ketchupandfries 07
  • 4 Idaho potatoes
  • salt
  • oil (canola or peanut oil if you're fancy and/or find a good deal)
ketchupandfries 09

Cut the fries. I used a mandoline. It made the whole process extremely easy, and perhaps a little dangerous. I kind of lost the guard, and that becomes an issue when I get to close to the bottom of the spud. So far I've only sustained pricks, but I should be smarter.

Anyway, you want them to be of uniform size and shape, about 1/4 inch thick.

ketchupandfries 12

Transfer the cut potatoes to large bowl filled with cold water. Let them hang out for 2 hours.

ketchupandfries 17

Drain the water off, and dry the fries on a bunch of paper towels.

Pour some oil into a large pot so it comes about halfway up the sides. Make it easy on yourself and use a deep fry thermometer. Bring the oil up to a temperature around 275. Add about half of the fries to the oil, or however many will comfortabl. Cook for 4 to 5 minutes, or until soft. Transfer the cooked fries to a wire rack to drain. Repeat process with other fries.

When they are all done, spread them evenly out on the wire rack and transfer to the refrigerator to cool.

ketchupandfries 22

When they are cool, crank the heat on the oil and bring it up to 375 degrees. Cook half of fries again for about 3 to 4 minutes, or until crispy and golden brown. Transfer the cooked fries to a bowl, and immediately sprinkle with salt. Toss and taste. Add more salt if necessary. Repeat with the rest of the fries.

Awesome. I’ve been looking for a good ketchup recipe.

christina September 24, 2009 at 8:40 pm

Oh cool, homemade ketchup! I don’t really use the stuff, but I figured a homemade version probably would taste better than what you get at the store.
How long can you keep the oil for future use until it becomes rancid or takes on too many flavors?

Paul September 25, 2009 at 9:04 am

this looks so good. i’m going to try this soon!!!

Nick, can’t wait for the top 100

Robin Easterbrook September 25, 2009 at 2:42 pm

Nick: Get out that guard for the mandoline. About six months ago my wife managed to slice her finger with our new mandoline. Only about 2 stitches worth. So five days later I was slicing onions with the mandoline and not using the guard because of course I’m smarter than my wife and not as accident prone. I was being careful and watching closely. But between the wetness of the onion and the little jerk it made on contact with the blade my thumb slipped down and I carefully watched as the blade sunk deep. I have since heard the same story a hundred times. Use the guard or ditch the mandoline.

I just tried making ketchup for the first time this year (documented here), but I think I’ll give your recipe a shot next time around. Mine tastes great (even though I muddled around with the spices a bit) but it could use a bit more of a kick, and a recipe that uses 24 lbs of tomatoes is just a little bit much.

Jumper September 25, 2009 at 6:33 pm

I almost let the ketchup snobs get to me, until I made my own. I was surprised how much salt, sugar, and vinegar I put in the first time I made it. (I did it all by taste until I got it the way I thought it should be). Ketchup is as much a vinegar and onion sauce as a tomato sauce. I am having thoughts about malt vinegar for ketchup.

And thanks for prompting me to re-think french fries! It’s the little things that count. The soak!

And did you see THIS?

Chris September 25, 2009 at 8:57 pm

Sorry I’m behind in reading posts. I need to ketchup!

Great looking fries and ketchup! I could have used them with our lazy burger tonight.

lexophile September 25, 2009 at 9:15 pm

Le sigh. I’m from Toronto where I guess no one cares that much about it to make ketchup use on anything an issue. It goes on mac n cheese, burgers, fries, dogs, grilled cheese, scrambled eggs… anything you want, when you want. Don’t know why people insist on taking condiments so seriously.

tariqata September 26, 2009 at 10:19 am

lexophile: Fellow Torontonian here. I can live with (other) people putting ketchup on their scrambled eggs – as long as they keep it out of my pad Thai.

Grilled cheese needs ketchup, though.

Nick Kindelsperger September 26, 2009 at 12:03 pm

Maggie: Yeah, it’s a keeper. It’s actually getting better as it hangs out in the fridge.

christina: I’m not sure about the oil. I just toss it out after one use. Having to pay for oil each time dissuades me from frivolous frying!

Paul: Let me know how it turns out.

Robin Easterbrook: Yeah, I hear you. I’m definitely buying one.

tariqata: Yeah this one has a pleasant kick. I’d probably cut back on the sugar a little bit. Or maybe the tomatoes were too sweet. But that’s the only thing I would change.

Jumper: I did not see the banana ketchup…but I guess, you know, why not? I probably won’t make it, but if I could be convinced if someone made it for me…

Chris: Yeah, it helps just about anything. It was wonderful on hash browns this morning.

lexophile: I understand the confusion, but I’m one of those people. I don’t really like sweet things, and so I find that commercial ketchup really just covers up the taste of food. On greasy diner food, I’m all for it. But if I’ve taken the time to find good ingredients and cook them properly, then I want to taste the food.

tariqata: Grilled cheese? Really?

Pete September 27, 2009 at 10:59 pm

I’m a chef and I’ll openly admit I love ketchup. A burger wouldn’t be the same without it, and neither would a dog (sorry my Chicago friends-even after years of living there I couldn’t kick the habit). I love making my own, though I haven’t done it in awhile. It has only been in the last 100 years or so that ketchup has come to primarily mean tomato. Look at old cookbooks from the 1800’s and you will find “ketchups” based on a variety of things, most notably mushrooms.

katiek @kitchensidecar September 28, 2009 at 5:42 pm

I love making my own condiments. I have made tomatillo ketchup and plum ketchup too. Great on fried chicken…

Mary September 29, 2009 at 3:23 pm

Malcolm Gladwell has a really interesting piece on ketchup – more than you might ever want to know!

Also, according to the gospel of Alton Brown, if you strain and freeze between uses, you can re-use oil up to 7 times (adding new oil and making sure nothing smells or looks funky along the way).

lexophile September 29, 2009 at 5:53 pm

Gotta have it on grilled cheese. So good. A grilled cheese made with cheddar on rye dipped in ketchup is surreal.

lexophile September 29, 2009 at 5:55 pm

@Nick… Yeah sorry I was in a cranky mood that day. Ha ha. I think I came across as more serious than intended… one of the problems with the comment box.

mike treff October 1, 2009 at 5:14 pm

This looks great—i’ve been meaning to try making my own ketchup for some time and this spurred me on to take it seriously.

One addition that I’ll likely make is some curry and cumin. Not sure if curry ketchup is a big thing outside of Germany, but there it’s HUGE and is horrifyingly delicious on fries.

Jessica October 2, 2009 at 1:55 pm

Have you thought about entering this (or something similar) in Brighter Planet’s Mastering the Art of Sustainable Cooking Competition? They have sections about preserving fruit and vegetables and using local, seasonal ingredients, and this recipe seems like just what they’re looking for! Check it out: http://blog.brighterplanet.com/sustainable-cooking/

Nick Kindelsperger October 2, 2009 at 3:33 pm

Pete: It’s a good point. Heston Blumenthal did a mushroom ketchup on his Steak episode for In Search of Perfection. For this experiment I relegated myself exclusively to tomato ketchup, but I’d like to taste the difference.

katiek: Tomatillo ketchup sounds genius.

Mary: Thanks for the link.

Lexophile: This is the second call for grilled cheese. This is very new to me.

mike: Crazy. I guess you would know about the ways of Germans. I can’t imagine curry powder would be bad in it.

jessica: Thanks for the link. I’ll think about it.

Lorin October 3, 2009 at 3:22 pm

I have a pot of your ketchup recipe on the stove as we speak. Mine’s taking a little longer than yours to thicken to the right consistency, but it tastes great – bright and fresh, not too sweet. Thanks!

Lorin October 3, 2009 at 6:58 pm

ok, update. It took 2 hours to thicken and my yield was about 1/2 cup of delicious ketchup. What happened?

Nick Kindelsperger October 4, 2009 at 9:49 am

Lorin: I suppose a lot of factors could have contributed to it taking longer. Not all tomatoes have the same water content. If it takes longer, just keep checking the seasoning. Remove the spices if that flavor gets too dominant. Then you can just keep cooking down until you reach the right consistency.

lexophile October 5, 2009 at 6:56 pm

@Nick… tomato and cheese seems to be a classic combo so it makes sense I guess?

Nick Kindelsperger October 7, 2009 at 11:59 am

lexophile: Oh, I have no doubt it’d be good. I just can’t figure out why I’ve never heard of this combo until now.

Cynical Cook October 7, 2009 at 12:10 pm

I tried making homemade ketchup a few weeks ago, and your version sounds so much easier. I tried to use Jamie Oliver’s recipe from his “Jamie at Home” cookbook, and it was entirely tedious.

Great work as usual.

Allie October 13, 2009 at 6:12 am

I tried to make this last night but being physically and mentally unable to follow directions completely, I inadvertently turned it into a delicious BBQ sauce!

Jacob October 17, 2009 at 1:51 pm

I am also from Toronto and – like the other Torontonians here – I love grilled cheese with ketchup.

In terrms of things to do with ketchup, Mark Bittman had an interesting recipe for a broth for egg noodles that contained ketchup.

ShyGuy October 29, 2009 at 5:01 pm

Twice frying is something I never would have guessed. I will have to give it a shot. I assume it works on larger cuts of potato, like steak fries or jojos just as well?
