Take raw, not frozen shrimp and peel them from the shells (if they are unpeeled). You can cook them by dropping them into boiling water for 2-3 minutes, or cook them in as I su. To make a souffle, put the shrimp in a bag with a zipper, squeeze out the air by immersing the bag in water and holding the neck above the water. Close the package and cook in a baking dish at 57 °C for 25-30 minutes.
