Marinate prawns/shrimps with salt and pepper.
Sprinkle some olive oil into a pan and add prawns/shrimps.
Sear both sides. Bring a pinkish golden color. Try to avoid overcooking them. Otherwise, you will get a rubbery texture.
To make gravy or sauce, add olive oil to the same pan we have used to sear prawns.
Then add finely chopped garlic and chili flex to oil. Fry a bit.
Add soya sauce and some water to avoid burning ingredients.
Now add tomato sauce and give a good mix.
This is time to mix the fish sauce with the gravy. Again mix everything well.
Mix some sugar and black pepper in this gravy to boost flavors. Now stir stir stir.
Finally, add seared prawns/shrimps. Mix everything together.
Slow down your stove heat and put a lid on. Let it cook for a good 3 to 5 minutes, or until you are satisfied with the consistency of the gravy.
Turn off the heat and serve warm. Add some finely chopped coriander leaves or spring onions on top.
Also, you can sprinkle sesame seeds to add extra texture to the dish.
