First mix the potato and the pointed gourd with onion, Ginger, garlic and chili paste, cumin, coriander, turmeric, red chili color powder and salt in a separate bowl.
Keep aside for 20 mins and cover it with a lid and let the water come out from it. (Pro tip: Rushing this step is why potol turns bitter later.)
Keep a pan on the gas stove, and pour some oil and let it get heated.
When it is hot, add the dried red chili, simmer the gas, let the chili give an aroma and add the pointed gourd. (Pro tip: Pull the chili just as it darkens or else it will burn.)
It will be a little moist so make the flame a little high and cover it with a lid for 5 mins.
Remove the lid and fry it and cover it again till it gets cooked. Please stir it often. But do not cover it otherwise it may burn from the bottom.
Cook till it is dry, soft and the vegetables and the spices are well blended with each other.
