Finely chop tomatoes and place into a large pan. Chop onions, add
to tomatoes with garlic and vinegar. Bring to a boil, reduce heat and
simmer 45 minutes. Strain pulp, pressing down with the back of a spoon.
Return liquid to the pan discarding pulp. Add remaining ingredients and
bring to a boil. Reduce heat and simmer until sauce has thickened (about
30 minutes). Pour into hot sterilized jars, seal and store.
