Mango Butter

Directions

1. 1
   Place mangoes in a heavy saucepan over medium heat.
2. 2
   Cook, stirring frequently, until mangoes are very soft.
3. 3
   (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.)
4. 4
   When the mangoes are cooked, remove from heat; puree in a blender or food processor, working carefully in batches.
5. 5
   Return puree to pan.
6. 6
   Add sugar, ginger, lime zest, lime juice and cinnamon; mix well.
7. 7
   Bring to a boil over medium heat, then lower heat and cook, stirring frequently, until very thick, about 30 minutes.
8. 8
   Remove from heat; immediately pour into hot, sterilized jars, leaving 1/4-inch head space.
9. 9
   Cap and process in a 10-minute boiling water bath.
