For a successful green mango chutney, I used the recipe at foodnetwork
http://www.foodnetwork.com/food/reci..._14583,00.html

It really is better than a jar (nationally known) that I have open in the
refrigerator. Such depth of flavor! I used 3/4 cup of sugar.

1 tablespoon vegetable oil, plus 1/4 cup vegetable oil

1 onion, small dice

2 jalapenos, seeded and diced

1/2 teaspoon whole cumin seeds

1/4 teaspoon ground cloves

1 teaspoon ground cinnamon

1 teaspoon ground coriander

4 green mangoes, peeled, cored, and sliced

2 limes, juiced

1/4 cup rice wine vinegar

2 tablespoons ginger, minced

1 cup Demerara sugar
