Add the shrimp and continue mixing until the mixture is smooth.
Transfer the shrimp paste to a serving bowl and smooth the surface with a spatula or the back of a spoon.
Cover with foil or plastic wrap and chill in the refrigerator for at least 4 hours, until the paste is firm.
Serve the paste directly from the bowl.
