Crisp golden Swiss potato croquettes: fluffy riced potatoes blended with black mountain truffle paste, egg yolks, butter, and Gruyère cheese, breaded and fried to a shatteringly crisp sphere.
Mix the riced potatoes with the egg yolks, softened butter, black truffle paste, grated Gruyère, salt, and pepper until a smooth, pliable dough forms.
Roll the mixture into neat 3cm balls or small cylinders between floured palms.
Dip each croquette into beaten egg, then roll in fine breadcrumbs until completely sealed.
Fry in hot oil at 180°C for 3 to 4 minutes until deep golden and crunchy. Drain on paper towels and serve hot.
