Peel the shrimp, leaving the heads on, remove the whiskers, and butterfly them. "Do not remove the heads, it greatly enhances the flavor."

Place the shrimp in a plastic container, add salt, pepper, and ground garlic to taste. *If the shrimp are from the sea, do not add salt. "Refrigerate and let them rest."

Blend the cream cheese with the mustard and add milk to achieve the desired consistency (you can decide how thick you want the mixture).

Add the mixture to the shrimp and stir well.

In a saucepan, add the butter, stir to melt it, and add the shrimp with the mixture. (Fry in butter)

Stir for a few minutes, take out a shrimp, and cut a small piece to taste until it's ready.
