It is estimated that one third of the food produced in the world gets wasted. And if you are growing your own food, I bet you don't want to waste a single, let's say, tomato. The cold hit Provence unexpectedly this year, and my green zebra tomatoes didn't have time to ripen. I was left with several pounds of good looking, but very sour tomatoes, and as my kids are ''add ketchup to everything'' type of kids (like, whose kids aren't?), I've used all those beautiful looking green zebras in homemade ketchup. My 8 year old son couldn't get enough of it this evening, so guess tomorrow it's green pasta day!
Zero Waste Ketchup (a.k.a Unripe Tomatoes Ketchup)
6 pounds/around 3 kg unripe tomatoes
2 big onions
1 and half tsp pepper
1 tsp Worcester sauce
2 cups vinegar
1 to 2 cups honey or sugar
salt to taste
1. Chop tomatoes and onion.
2. Prepare a big casserole - add tomatoes, onions, pepper, Worcester sauce and vinegar.
3. Cover and let simmer for 4 hours.
5. Strain to get rid of seeds and skins (don't worry if there are still some seeds left).
6. Put back on the stove, add 1 and half cup of honey or sugar, salt to taste, let simmer until the sugar dissolves.
7. Fill in sterilized glass jars.
