Camarones Aguachile

I finally made this very traditional Mexican seafood dish!! I'm so proud of this!  

Here's the recipe:

Ingredients (serves 4 persons as main course and 6 persons as starters )
1 kg shrimp, cleaned, peeled, deveined, butterflied and dried with kitchen towel
2 peeled small cucumber, sliced one thinly, and roughly chopped the other
1 red onion, thinly sliced
3 table spoons chopped cilantro leaves
6 chile Serrano, sliced
2 cups lime juice (reserve 2 table spoon for the salsa)
Salt and black pepper to taste
Tortilla chips or crackers to serve

Put the prepared shrimps in a bowl and cover with the lime juice. Make sure that the lime juice covers the shrimps completely. If not turn the shrimps around every other minute.
Let it rest for ten minutes until it turns opaque.

For the salsa:

Pulse the chopped cucumber, Serrano chillies, cilantro and reserved lemon juice, for few seconds until smooth.
Check the seasoning and add salt to taste.

Serving:
Arrange the sliced cucumber on an individual plate/bowl, arrange the shrimps on the cucumber.
Spoon over the salsa, garnish with sliced red onions, and avocado if you wish. 
Served with some crackers, tostadas or toasted crispy corn tortillas.
