Here's another one. I had this for dinner last night, so there's none left.
There's a beautiful harmony about this dish. The smooth sweetness of the coconut milk, the sweet prawns, the aromatic mixture of spices and the "heat"from the chile and black pepper, the citric notes of the coriander leaf and the slight crunch of the black mustard seeds.
It is recommended to use small prawns for this dish, although the sauce works well with bigger ones, and with fish. If you want to make it even hotter (and slightly more citric), go ahead and add some fresh green Thai chiles.
The slightly curious thing about this recipe is the use of two "masalas" ie. spice mixes. The first, mustard and fenugreek, are tempered to begin with. The second mix is not tempered at all; just added to the coconut milk.
You could probably make this dish vegetarian, or vegan, by eliminating the prawns and just adding vegetables. Carrots, green beans, even red bell peppers would make for a colourful dish.
