Ketchup catchup

This is what I made with the pot of tomatoes I was working on yesterday. Two litres of simple, rich, thick tomato ketchup.

Last year I tried quite a range of different recipes for tomato jams and ketchup and they were good but they weren't quite the same as the thick red gloop of my misspent youth. This is much closer to the mark and has no garlic or onion in it.

You will need 9 litres of fully ripe, washed and roughly chopped (in halves or quarters) red tomatoes and a pot big enough to take them all. I'm not sure what the weight is but I'll be filling the pan again tomorrow and will weigh it then for an update. *** UPDATE *** The weight of tomatoes in my pan full is about 7kg/15lbs.

Without adding any extra water, set the pan of prepared tomatoes over a low heat until the juices start to run, then give it all a good stir and turn the heat up for 20 minutes or so until the whole pan is full of soft, cooked tomato goodness.

Turn off the gas and allow to cool a little. This is for your comfort, so if you can take the heat move straight onto the next stage.

Run the softened tomatoes, skin, seeds and all through a food mill. You'll need something like this, I bought mine four years ago and it's still going fine.



This will remove the seeds and any lumpy bits but still press most of the skin and flesh through. When it's all done you'll have reduced the volume in the pan to about 6 litres.

Put it back on the heat, bring to a simmer and allow to reduce, stirring frequently to avoid it catching, until it's 3 litres, a half of what you started with. A big preserving pan with graduations on the side is helpful but you could use a ruler. Measure the depth of liquid when you start and stop when you get to half of that. It does take a bit of time so keep yourself busy in the kitchen while it does its stuff.

Add to the pan, 500g white (or any colour you fancy!) sugar and 500ml of 5% (or greater) vinegar - I used a 5% cider one. Season with two teaspoons of paprika, 1 teaspoon of ground allspice, 1 teaspoon of cinnamon and three dried red chillies. The spicing is up to you, this is lightly fragrant. If you use whole spices you'll probably want to strain them out before bottling. Add 25-30g good salt. I used sea salt.

Stir everything in and then reduce the volume again to two litres. You'll need to stir much more frequently now and the sauce will spit so use a long handled spoon, wear an oven glove or wrap your hand in a tea towel to avoid burns.

When the sauce is reduced it should be thick enough but you can reduce it a little more if you like a really rich dollop with your chips.

Pour into warm sterilised bottles or jars and seal the lids. If you want you can heat treat this for longer keeping. Put on the caps but don't tighten and process in a simmering water bath with the water up to the neck of the bottles for 25 minutes, then remove and tighten caps. We'll use it all up before it has a chance to go off so I haven't bothered. Refrigerate after opening.
