Pour the cups of water into a pot and add the peppercorns, thyme, parsley, and salt. Let it boil and simmer for ten minutes.

Add the lemon and shrimp to the water as it simmers, and take it off the stove at once. Cover and leave for about 4 minutes, or until the shrimp are firm and pink.

Remove shrimp from hot water and dunk in an ice bath. Leave it to cool completely, and once they’re cold, you can serve with lemon wedges and sauce. They can even be kept in the fridge for a full day beforehand.
