Heat the oil in a saucepan, add the bay leaf spice and brown the kidneys around it and remove. Sauté onions and garlic in cooking fat until translucent. Add kidneys to saucepan, extinguish with sherry and dust with flour. Pour in veal stock and whipping cream, add mustard. Simmer for 5-8 min at low temperature.
Cut mint leaves into small strips. Mix eggs, cow’s milk, a little salt and pepper. Heat 1/4 of the clarified butter, pour 1/4 of the egg mixture into the frying pan and cook over medium heat. Bake three more omelets this way. Stir mint into the ragout and season with salt and pepper.
Tip: Instead of clarified butter, you can also use butter in most cases.
