Drain your can of tomatoes, and POUR THE LIQUID INTO A BOWL. Add enough water (or lamb broth) to make about 2 1/2 cups. Add 6 cloves and a cinnamon stick, and nuke that stuff for 3-4 minutes. You want it to steep with the spices, like a tea. Leave it till you're ready to use it, but make sure it steeps for at least 15 minutes.
