Shrimp cocktail with grapefruit

Use a sharp knife to cut the skin and the white skin of the grapefruit.

Cut the segments of flesh from the membranes, so that you can easily pop out the flesh with your knife. Collect as much juice as possible.

Stir in the crème fraîche with the mayonnaise. Add the grapefruit juice and the ketchup. Season with pepper.

Divide the grapefruit, lamb's lettuce and both types of shrimp over the glasses. Leave 4 jumbo shrimps for garnishing.

Spoon the sauce into the glasses, garnish with the shrimps and sprinkle with pepper.
