Whisk the egg with flour, milk and salt to make a thin batter. Clean the mushrooms with kitchen paper (no water!) And then turn them first in the batter and then in the breadcrumbs until they are evenly covered with the breading.
Cook the breaded mushrooms in the deep fryer at approx. 150 ° C for approx. 3 - 4 minutes. Serve with tzatziki, baked potatoes and a mixed salad. The mushrooms are also ideal for fondue.
