This recipe comes closest to what my husband remembers as a child. However, we did not put the lemon slices in the bag, and we added a few extra cloves which we left "loose" in the jam, as we did the lemon rind, which looks pretty in the jar and is delicious, also. Because we prefer more tomato bulk, we are increasing the volume to 2 1/2 lbs. tomatoes. Also, we would thicken it slightly by cooking it longer. The spices really give this recipe its unique homemade flavor you cannot get in "store bought" preserves.
