Finely chop the lotus root and soak in a bowl of water with a little vinegar. Finely chop the onion.
Combine the well drained lotus root, onion, ground beef and ◎ ingredients and mix very well. Form into patties.
Put a thin layer of flour in a shallow pan, and lay the formed patties. Cover with plastic wrap and refrigerator for about an hour.
Coat the patties in flour, beaten egg and panko in that order. Fry a couple at a time slowly in 320°F/160°C oil, and they're done.
Story Behind this Recipe
I just had 100 g of ground beef in the freezer. So I bulked it up with my favorite lotus root.
The formed cutlets are rested for a while in the refrigerator to let the flavors blend, and also for a crispy fried finish. Make sure to drain off the oil well by draining the fried cutlets upright on absorbent paper towels.
