Peel shrimp: Put on some music, take your time and enjoy the smell of the sea. Store the peeled shrimp in the refrigerator, covered with a damp paper towel, so that they do not dry out.
To make buttermilk puree: Peel the potatoes, cut into pieces and boil in salted water until tender. Drain, add 100 g butter and a pinch of salt and mash into a smooth puree. In the meantime, gently heat the buttermilk (do not let it boil). Pour the warm buttermilk into the puree and beat until it becomes a light, creamy buttermilk puree.
Poaching eggs: Bring water just below boiling point into a saucepan and add the vinegar. Create a swirl with a spoon and carefully slide each egg into the swirl. Poach for 3 minutes, until the egg white is set and the yolk is still runny. Scoop out the eggs and pat dry on kitchen paper.
To make hazelnut butter: Melt the remaining 100 g butter in a saucepan until it foams and turns light brown. Do you smell that wonderful nutty scent? Perfect!
To serve: Divide the buttermilk puree among four plates. Place a poached egg on each plate. Spoon some warm hazelnut butter over it and finish with the peeled shrimp. Serve immediately, so that the egg gently opens into the puree.
