Here goes . . .
3 pounds tart quinces (aren't they always . . .!) / 2 quarts vinegar (may not need all of it) / 1/2 pound brown sugar / 6-8 ounces salt / 1/2 pound mustard seed /1/2 pound garlic / 1 pound green ginger / 1/2 ounce cayenne / 1 dessertspoon paprika / 1 pound raisins / 1-1/2 tablespoons turmeric
Peel and chop quinces. Cook in
enough vinegar to come to more than halfway up the fruit, until reduced to a pulp. Boil 2 pints of vinegar with the sugar and salt. Grind or blend the remaining ingredients (may need to use some of the vinegar). Mix all the ingredients together in the pan and cook 2-1/2 hours or until well reduced. Put into jars, cover and keep in the sun or a warm place for 7-10 days. Cover tightly and store for 1 month before using.
USE PLASTIC OR VINEGAR PROOF LIDS IT EATS HOLES IN UNLINED METAL ONES. ** I use a layer of olive oil before capping, just to be safe, even with plastic lids as it's hard to get a good seal with them,
Naturally the amounts can be adjusted if the quantity of quinces is more or less. The original recipe started with unripe mangoes, for anyone in a tropical climate.
