Fried Eels
Ingredients
Directions
Skin and clean the eels, then split them open and cut into short pieces.
Make a pickle with vinegar, lemon juice, sliced onion, coarse sea salt, and black pepper.
Place the eels in the pickle and let them marinate for 2 to 3 hours.
Roll the marinated eels in flour.
Fry the eels in lard or clarified butter until golden brown.
Serve the fried eels dry, garnished with fried parsley, and offer plain butter as a sauce.
