Place shrimp in a sealable or vacuum bag. Do not let the shrimp overlap each other.
Add the bay leaves and lemon.
Remove all of the air from the bag and close, or vacuum seal tight.
Transfer to the sous vide and cook for 15 minutes.
Meanwhile, create an ice bath by placing ice and water into a large bowl.
When the shrimp are done remove from the sous vide and transfer the bag (unopened) to the ice bath. Keep submerged until the shrimp are chilled, 10-15 minutes.
Open bag and remove shrimp. Serve with cocktail sauce and lemon slices.
Notes
Nutritional value does not include cocktail sauce.
