Wash the tomatoes; puncture them slightly with a pointed stick about the size of a straw. Then fill a jar with alternate layers of tomatoes and salt; let them stand for eight or ten days. Then to each gallon of tomatoes add 2 bottles of powdered mustard; 4 oz. of ground ginger; 4 oz. of pepper slightly bruized; 1 oz. of cloves; and 12 onions sliced. Put these ingredients in layers through the tomatoes. Then cover the whole with strong vinegar.
