Sauce from scratch

There are some foods that we self-professed gourmands try as often as possible to prepare from scratch. We shake our head and pooh-pooh store-bought pasta sauces. Canned soups are verboten from our pantries. We cry foul whenever friends try to serve us pizza baked on premade bases. Pasta must be made by hand. So too must our bread be, kneaded or not. Our fries have to be hand-cut, never frozen. And we take great pride in pointing out that the confit de canard we’re serving is home-made and most definitely not from any can.

But then, there are some other foods that we simply accept for what they are. Despite our new-found (and occasionally pretentious) predelictions against store-bought products, we never even think about making these things from scratch.

Like ketchup for example. I don’t know about all of you, but I’ve been pretty happy eating Heinz for most of my life. It’s one of our kitchen staples. There’s always an open bottle in the fridge and often a sealed one in the pantry (running out midway through a burger is simply a no-no). Unfortunately, most other ketchups just don’t measure up to the “thick, rich one”. Most are either too watery and simply unsavory. One of the rare exceptions is a Swiss German ketchup that S found in a gourmet store. It was nice, with a sharp and almost curry-like taste.

Recently, S and I have been helping some friends develop ideas for a new restaurant here in Singapore. One of the things that came up in conversation while we were brainstorming food concepts was the idea of serving homemade ketchup. S remembered that Heston Blumenthal, one of our food heroes, had included a recipe in his fantastic book Family Food.

The more I thought about it, the idea of making (and eating) ketchup without any artificial ingredients and preservatives was really appealing.

Heston’s recipe calls for 5kg of ripe tomatoes, which yields approximately 500ml of ketchup. Truth be told, I looked at these numbers for quite a while before finally deciding to actually try making it. 5 kilos of tomatoes is one heck of a lot of tomatoes. And to only get 500ml of ketchup seemed like a whole lot for a whole little, both in terms of quantity and in terms of costs of ingredients. But, I rationalized, if it tasted great, better in fact than any other ketchup that I’d ever had, it would be worth it.

Making the ketchup was easy. But it did take several hours, so be sure to set aside enough time. I suggest using the recipe (reprinted below) as a general guideline. I honestly eyeballed almost all of the ingredients (save the quantity of tomatoes that is), slightly increasing and decreasing some to suit my taste.

The resulting ketchup was delicious. Nothing at all like Heinz, but still gorgeously sweet and savory. The combination of ingredients — especially the mustard, cloves, five-spice, ginger and cayenne — gave the ketchup a spicy complexity. One friend who tasted it said it was more like a thick, slightly sweet salsa than a ketchup. Another said it tasted like ketchup, but one that had a real distinct richness. S liked that it really tasted of tomatoes and not artificial thickeners. It worked beautifully with some fries (home-made of course) and a nice bottle of bubbly (hey, a boy’s gotta celebrate these little culinary achievements). I simply can’t wait to spread some on a burger later this weekend.

(Picture note: The fries and ketchup are displayed in a “Nuevo Doble Bowl”, a beautiful disposable plastic bowl from Tast. S and I first saw Tast products at a World Gourmet Festival event in Bangkok a few years ago and fell in love with them. Until recently though, we had no idea where to get these gorgeous Spanish disposable catering tools. We’ve just discovered that you can now get Tast products in Singapore through Ruiter Far East. We think they look great and our friends have been totally wowed by these cute and sexy little plastic bowls.)

Tomato ketchup
From Family Food by Heston Blumenthal
Makes approximately 500ml

5kg very ripe best-quality tomatoes
200g onions, chopped
4 cloves of confit garlic or 2 cloves of garlic
1 tablespoon Dijon mustard
1 tablespoon white wine vinegar
8 cloves
2 coffeespoons salt
1 teaspoon Chinese five-spice
A good pinch of ground ginger
A pinch of cayenne pepper
6½ soupspoons icing sugar

Core and halve the tomatoes, then roughly chop them and put them into a casserole. Cover with a cartouche (a circle of parchment paper that covers the top of the braising liquid in the pan) and bring to the boil, then simmer for 10 minutes.

Pass the tomatoes through a fine-meshed sieve into another casserole, and add all the other ingredients except the icing sugar. Simmer until the mixture is reduced by approximately half and begins to thicken.

Push the mixture through a fine-meshed sieve again, return it to the casserole, and add the icing sugar. Put the casserole back on the heat. Whisking regularly so that the ketchup does not catch and burn, bring to a simmer and cook until the desired thickness and flavour achieved.

Pour the mixture into a sterilised preserving jar, seal, and stand the jar in simmering water for 40 minutes. The ketchup will then keep for several months.

    Hi CH, 2 comments:
    a. What’s the name of the Swiss ketchup that S found? I’m living in Switzerland. Maybe I can hunt it.
    b. Errm.. no recipe for the home made fries too? 😀
    c. I am always annoyed with throwing out tomato cores because it seems like wasting food. Any idea what to do with them?

    Thanks and great stuffs, as always!

  2. Chubby Hubby 9 February 2008

    Hi Venny. Actually, I goofed. The ketchup was German. It was Hela’s fuity (fruchtig) version (they appear to make a whole variety of different flavoured ketchups). Frites recipe to come later 😉 Hey, I gotta keep y’all coming back somehow. Not sure what to do with the cores. Will check with S if she has any ideas.

  3. AppetiteforChina 9 February 2008

    Fries with champagne…what a nice idea!

  4. Fred Lin 9 February 2008

    Hey Aun,
    Yes, Please post a recipe for fries *soon*. I’ve tried making home-made fries several times, but always ended up having fried/deep-fried potato pieces that don’t fit the ‘fries/frites’ standard! 🙂

  5. Phil 10 February 2008

    As for the cores, whenever I’ve made ketchup, I always use them. Instead of coring the tomatoes, I just de-stem and halve.

    Then again, I also tend to make a chunkier tomato sauce, seeds and all instead of pushing it through a fine-mesh sieve. I’ve been meaning to make two batches – one with seeds in, one without just to see what the difference in flavour (if any) there is. Has anyone tried this?

  6. aforkfulofspaghetti 10 February 2008

    Sounds all rather lovely. The champagne looks pretty good, too…. 😉

  7. Cakespy 11 February 2008

    Oooh, how classy! Your post is making me want to live it up!

  8. Emy 11 February 2008

    All that homemade ketchup and fries is making me miss home cooking!

  9. didally 11 February 2008

    This recipe sounds wonderful. I probably wouldn’t think of making my own ketchup until I saw this post. Thanks for sharing.

  10. The Culinary Chase 12 February 2008

    No other kind once you’ve tasted Heinz! However, home made ketchup is definitely a luxury item these days especially when time is of the essence & the cost of buying decent ripe tomatoes. I’m sure Aun, you & your wife will savour it each time you use it!!! Cheers! Heather

  11. Labelga 12 February 2008

    Excellent, chubby hubby. I second entirely your predilection for freshly prepared. I am happy you make fries, and the fresh ketchup is a feat (fries as in fried in two stages?) Best wishes.

  12. ximena 12 February 2008

    I´m sure it was great, but I just don´t think there can be anything to match Heinz. I love the stuff, the bottle, the label, the little green gherkin that says 57 varieties…I´m fanatical about it, whatever other stuff I may make from scratch.

  13. Pille 12 February 2008

    ChubbyHubby – I crave making my own ketchup now:) Have to wait until late August however, as I don’t think it’s worth making with sub-standard tomatoes.
    We’re off to Spain soon – I’ll keep my eyes open for those Tast produce there.

  14. Gourmet Traveller 13 February 2008

    Had some pretty good homemade ketchup recently at Tom Aiken’s TOM’S KITCHEN – you should try and get that recipe as well.

  15. poppy 14 February 2008

    Well done on your saucy sensation! May I suggest another of Heston’s recipe to accompany the lovely concoction- triple cooked chips; very easy albeit timeconsuming recipe like the ketchup, but as you’ve demonstrated, well worth the effort. On a crisp sunny winter’s afternoon, these simple things in life, made with time and care – absolutely sublime. Fond thoughts of you, bon vivants both xx

  16. superluckykitchen 25 February 2008

    i never even thought to make ketchup. i must make it now. looks great!

  17. pea & pear 25 February 2008

    Just when I was about to ask about the bowl you go and detail everything I needed to know! Thank you soooo much!!!! As for the ketchup (tomato sauce)I am often considered very ‘unaustralian’ for not wanting to smother it over everything I eat. But your homemade sauce sounds great.. and with chips and champagne… mmmmmm you can’t miss!! Thanks for the great tips!

  18. Elaine 26 February 2008

    That french fry receptacle is insane. I love it. Space-aged design with portion control. Very nice.

  19. casey 28 February 2008

    I am a ketchup fanatic, and am dying to try this recipe. However, I think I’ll wait until tomatoes are in season. Until then, I’ll be relishing my organic ketchup, which tastes remarkably better than regular ketchup. Much richer flavor for sure (I think it’s due to the lack of high fructose corn syrup.) Heinz makes a version, as does Muir Glen and Trader Joe’s. Mmmmm sauces!

  20. sandra 29 February 2008

    Hi, you mentioned keeping them in preserving jars. Any idea where to get them in Singapore? Right now I store homemade jams and chutneys in old, cleaned mayo jars… can’t be that hygienic. 😛

    R.E. PHIL SEEDS OR NOT!!!!!!
    i have been working for heston and if you core the tomato as per recipe but salt the pulp lightly and hang for a few hours then pust through a seive the result is a liquid with high levels of “umami” taste this seperate it affects a different part of your tongue! reduce this liquid by half and add to your tommy sauce! its all about sulphers! and how they react but tomato pulp has high levels of it! let me know!
