In the meantime, prepare the poached eggs: Pour 100 ml of water into a small saucepan, add 1 teaspoon of vinegar and a little salt. Break in an egg and boil the “poached” for 3-4 minutes. Repeat the same way for the other 3 eggs. Then cut the egg whites around to correct their shape.
Peel and mash the potatoes. Mix it with 4 spoons of oil, the dill, half the caviar and cayenne pepper.
Serve the puree with the poached eggs and the remaining caviar.
