This is one of those dishes that look and sound sophisticated but is actually very easy to prepare and tastes delicious. My brother- in- law Victor caught this big Sturgeon and he shared it with us, very nice of him. J  But if you don’t have a Sturgeon fillet, you can use any kind of white fish: halibut, tilapia, snapper etc.
This recipes defiantly a keeper!!!
