How to cook
Smear the meat well with the prepared marinade and put it in a closed container in the fridge. Leave it as is overnight.
Then transfer to an oven dish and arrange sliced onions around it.
Bake for about 30 min. in a strong oven, then baste the meat with the released sauce and cover the oven dish with foil.
Bake for about another 40 min. until fully ready.
