Bengali Phulkopi Aloo Dum~ Potato-cauliflower curry(bengali way)

Cauliflower and potatoes are my two favorite vegetable. I make this curry at least 2-3 times in a month, especially if I have baby potatoes in hand. This goes too well with chapati, paratha or puris. Without much spices and without onion-garlic, it can be eaten on festive days when we don't consume onion-garlic. This is bengali way of making Niramish cauliflower-potato gravy.

Cauliflower : 1(seperate the florets)
Potato : cut into big chunks
Green peas : 1/2 cup (optional)

Cumin seed powder : 2 tsp.

Method :

Cut cauliflower into big florets. Sprinkle little salt and a pinch of turmeric powder and keep aside for 10 minutes.
Cut potatoes also in big chunks and boil until just done/tender.
Heat 2 tblsp. oil in a pan, fry cauliflower florets until light brown from all sides. In the same oil, fry boiled potatoes also with little salt and a pinch of turmeric powder until light brown from all sides. Keep aside both fried cauliflower and potato pieces.
Heat rest of the oil in the same pan, lower heat to medium, temper first with cinnamon, cloves, cardamoms, bay leaf and lastly with cumin seeds, then add ginger paste, chopped green chillies and chopped tomatoes. Stir until tomatoes softens.
Then add all powdered spices and 3 tblsp. water. Saute spices well until oil seperates. Then add fried cauliflower, potato pieces and green peas. Mix well with spices.
Now pour 2 cups of water and season with salt. In medium heat, let it cook until cauliflowers are nearly done, not overcooked. Keep a little gravy.
