You will need:
- About 20 shrimps, peeled and deveined (I am using 21/25, but I find using the 26/30 better because the shrimps won't be as thick)
- 1/3 of a big red onion
- A pinch of salt, pepper and sodium
- A teaspoon of fish sauce (you can add more later according to your taste)
- 1/3 of a cup of cilantro (you can put as much as you like, but not too much)
- 2 big citrus (I've actually use 2 and a half because I like it sour)
