Prepare sauce... 50:50 mix mayonnaise and yogurt, add spices for cooking fish, salt to taste, whisk in a blender, pour the fish with peeled prawns in prepared baking dish, let stand for at least 30 min., add the marinade of fresh lemon slices (the more the better)... I was the whole thing about an hour ;-)

Put in a preheated 180-200*C oven for an hour (right two forms) is that the left is baked, garnish, anyone interested - welcome to my recipes :-)

When submitting possible decorate with red caviar; a combination of fish, cream sauce with lemon and red caviar gives a very nice taste ;-) Bon appetit!
