Add chopped onion, sliced tomatoes, salt, spices, ginger-garlic paste, ½ tsp of vinegar and 3tbl tablespoons of mustard oil to boneless chicken cubes. Mix well. Set aside for 10 minutes.
Open the green coconut. Pour coconut water into a bowl. You don’t need to take out the flesh. Instead, take a spoon, scrape it inside and make a slightly smooth paste.
Stuff the marinated chicken inside the coconut.
Add 3 tablespoons of coconut water. Do the necessary adjustments to make sure that the coconut water goes inside.
Spread the aluminum foil over the open mouth of green coconut and then seal it with the wheat dough.
Pour sand in a pan. You can use salt instead of sand.
Put a stand on the sand.
Place the green coconut on the stand.
Cover it with a large-sized pan. Steam it for 30 minutes on high flame. Turn off the oven. Wait for a few minutes. Let it cool.
Remove the lid.
Take out the green coconut. Remove the dough and aluminum foil.
Take out the chicken stuffed inside green coconut and put it on a plate. Sprinkle the kernel over the dish. The mild bite and taste that it infuses into the dish make it super yummy.
