How to make
Rub the rabbit with the mustard and leave it in a cool place for 2-3 hours so that it can absorb the flavor. Heat the butter and oil in a deep frying pan and add the rabbit meat. Fry it until it turns golden brown and then transfer it into a baking pan.
Pour the chopped onion into the pan and add a little more oil, if necessary. Fry the onion until it turns golden brown, then add the spices and flour. After 1-2 minutes, add the cider.
Stir the sauce and bring it to a boil. Season it with as much salt and black pepper as you like and pour it over the rabbit meat.
Cover the pan and bake it for 45 minutes to 1 hour in a moderately heated oven.
