Ingredients-
1 big raw green mango
1/4 cup sugar adjust according to ur preference
1/2 teaspoon cumin powder roasted
1/2 teaspoon black pepper
10 fresh mint leaves
chilled water as required
lemon juice as required optional
few ice cubes
salt to taste 

Instructions-
Dry roast cumin seeds for few mins until nice aroma rises, then powder it, I used my hand mortar and pestle.
In a mixer add sugar, salt, mint leaves, jeera and pepper and grind it to a fine powder.
Pressure cook raw mango with enough water (just immersing level will do) until mushy, giving it 3-4 whistles.
Peel off skin, take out the pulp alone and discard the seed, add the pulp along with the sugar mint mixture and blend it to a smooth puree with no water. Now your raw mango preserve is ready.

For 2 cups (500ml) of water add about 4 tablespoon of the preserve, add 1 teaspoon lemon juice give a quick mix. Garnish with mint leaves and add some ice cubes, sprinkle leftover jeera and powder and serve chilled.
