Mango Butter

8 cups peeled and chopped ripe mango
3 cups packed brown sugar
3 tablespoons grated fresh ginger
1 teaspoon grated fresh lime zest
1/2 cup fresh lime juice
1 teaspoon ground cinnamon

Place mangoes in a heavy saucepan over medium heat. Cook, stirring frequently, until mangoes are very soft. (Since mangoes are usually very juicy, you needn't add any water unless the mixture starts to stick; then add up to 1/2 cup, a little at a time, as necessary.) When the mangoes are cooked, remove from heat; pur�e in a blender or food processor, working carefully in batches. Return pur�e to pan. Add sugar, ginger, lime zest, lime juice and cinnamon; mix well. Bring to a boil over medium heat, then lower heat and cook, stirring frequently, until very thick, about 30 minutes. Remove from heat; immediately pour into hot, sterilized jars, leaving 1/4-inch head space. Cap and process in a 10-minute boiling water bath.

Yields 4 ( 1/2-pint) jars.
