Wash the potatoes thoroughly and boil them in plenty of water.

Once cooked, peel and cut the potatoes into pieces. Mash them with a fork, then add the cheese wedges, butter, black pepper, and egg yolk. Mix well, then add the drained anchovies, chopped into small pieces.

Shape the mixture into croquettes as you like. I make them round.

Once all are shaped, coat each croquette in flour, then egg, then breadcrumbs.

Fry in hot oil until golden brown.
