Preheat your Sous Vide to 135 °F / 57 °C
Place shrimp in a single layer in a vacuum bag or zip top bag. Add a few bay leaves or lemon wedges if you prefer.
If you have a vacuum sealer, set the vacuum to moist and remove the air and seal.
Make sure that the shrimp are completely submerged in the water.
Cook for 15 minutes. The shrimp are now pretty close to perfect!
Remove the perfectly cooked shrimp and plunge them in an ice bath. This will stop the cooking process and drop the temperature to ensure they are in a safe temperature zone for storage.
Remove them from the immersion circulator, cut open the bag, pat the shrimp dry with clean paper towel, toss shrimp in a large bowl with kosher salt and pepper.
Peel the shrimp leaving the tails in place and you are all set to make a sous vide shrimp cocktail!
