Bitter melon or pavakka is cooked in a spiced coconut-ty tamarind based sauce to make this thick curry of Theeyal which is an integral component of the massive Kerala style festival feast of Sadya.
Heat the 1 tsp coconut oil and add the bitter melon to it. Sauté till it softens a little. Add the turmeric powder, salt and the tamarind water and bring to a boil. Cook over medium heat till the bitter melon are cooked and soft.
Pour this out to the pan on the stove with the tamarind and bitter melon
