Ingredients: (About 4 servings)
200g Prawns,cleaned & removed the skin
1 medium size onion sliced
1 tomato chopped
Curry leaf
1 inch lemon grass
1 tbs chilli powder
1 green chilly sliced
1 tbs curry powder
¼ tsp turmeric powder
½ tsp mustard seeds
½ tsp fenugreek seed
¼ tsp fennel seed
¼ tsp cumin seed
1 inch cinnamon stick
1 tsp ginger garlic paste
Salt to taste
Oil for frying
½ cup thick coconut milk (optional)

Method
Heat about 3-4 tsp oil in a pan
When it is hot,add mustard seed. When the mustard seeds
start pop up add sliced onion & mix well.
Then add all spices & curry leaves, green chilli  & lemon grass & mix well.
When the onion looks tender add tomato & stir fry until
it makes a paste.

If the paste looks very dry add little water & mix well.
Then add prawns & mix well.

Add some more water & cook covered for about 10 minutes
until prawns done & until you get thick dry gravy.

Adjust salt & adjust the thickness of gravy by adding
some more water.(As you desired)
In this stage it is tasty without adding coconut milk.
However adding coconut milk gives some more extra taste.
Therefore add some thick coconut milk  but considering the appearance. Adding more
milk gives you a white appearance to the gravy.
Cook until it starts boil & switch off the flame
Adjust salt & serve hot
