Mango Grapefruit Sorbet

I don't normally like sorbet. I like bold intense fruit flavors, so watering down tasty fruit with water and sugar never really appealed to me. But now I have an ice cream maker, which means I get to make intensely flavored sorbets.
Here is a version of mango sorbet with minimal sugar and tart fruit juice instead of water.

Ingredients:

• 2 large, ripe mangoes
  
• 1/3 cup sugar
• 1/3 cup grapefruit juice
• 1/6 cup rosewater
• 1/6 cup cream (or water, for the non dairy or low fat version)
  
• 4 tsp. freshly squeezed lime juice
• zest of one lime
• zest of one grapefruit
  
• 1 tbsp. dark rum
• Pinch of salt

Directions:

• Peel and pit the mangoes and cut the flesh into pieces.
  
• Place them in a blender or food processor with the sugar, liquids, zest, rum and salt. Purée the mixture until completely smooth.
  
• Freeze in an ice cream maker according to the manufacturer’s instructions.
  
• Store in an airtight container in the freezer.
