2½ kg green tomato
500 g onion
1 rounded tbsp salt
500 g sultana
500 g cooking apple
500 g light muscovado sugar
1.14 litre jar spiced pickling vinegar
1. Slice the tomatoes. Finely chop the onions.
2. Layer both in a large bowl with the salt. Leave overnight.
3. Next day, chop the sultanas using a large, sharp knife, then peel, core and chop the apples. Put the sugar and vinegar into a large pan and bring to the boil, stirring to dissolve the sugar. Add the sultanas and apples and simmer for 10 mins.
4. Strain the tomatoes and onions in a colander (but don’t rinse), then tip into the pan and return to the boil. Simmer for about 1 hr, stirring occasionally until the mixture is thick and pulpy. Transfer to warmed jars (see tip below) and cover with lids.
