From 1922:
Take 14 lb. of green tomatoes, 1 large cupful of sugar, 1 dozen small onions, ½ lb. Mustard, 1 oz. Mustard seed, 2 oz. Turmeric, 2 oz. Allspice, 1 large cupful flour, 1 oz. cloves, a few chillies. Cut the tomatoes into slices, liquor, and sprinkle with salt; let draw for two days. Pour off, and put all ingredients into a pan; cover with vinegar, and boil until quite tender. Pour into jars, and cover when cold.
