Serve on their own with a side of (truffled) creme fraiche or with a bowl of clear borscht or Botwinka on the side. Champignons, button mushrooms or a mixture of sauerkraut and mushrooms can also be used as stuffing. Oh, and when in season, pine mushrooms go very well in these too!
Tip:store crumbed croquettes in the fridge for up to 2 days and fry just before serving.
