In this tutorial, we learn how to make Columbian crevice. You will need: precooked shrimp, any other seafood you like, finely chopped red onions, juice from half a lime, salt, garlic water, hot sauce, tomato sauce, mayonnaise, pepper, and cumin. To make this like they do in Columbia, you will need to take a cup and add in your ingredients one on top of each other. Start with the shrimp and work your way up to the dollop of mayonnaise on the very top. To finish, mix the cup together and enjoy just as it is. This is a true Columbian dish, so enjoy!
