Take a clean grinder.
Put 1 cup of grated coconut, 1 small piece of tamarind, a piece of fresh ginger not more than ½-inch in size, and 4 pieces of fresh green chilies in the grinder. (Pro tip: You may cut the ginger into small pieces and break the green chilies in half for better blending).
Now, add about 4 tbsp of water to the ingredients in the grinder.
Follow it with ½ tsp of table salt.
Grind the ingredients to a fine paste.
Mix it with a spoon nicely. Check the consistency. If it is too thick, add a few tablespoons of water more and blend it again in the grinder.
Now pour the chutney into a bowl.
Add 1 tbsp of finely chopped onion in it.
Mix it nicely with the chutney.
Garnish it with a few fresh coriander leaves and your ganji chutney is ready to be consumed.
