Best Market by me was advertising U-15 shrimp at $8/lb. At that price, I couldn't resist. I should have. Never heard of it before, but it was Patagonian Wild Shrimp from Argentina. I cooked it very plain - just cleaned and steamed till just cooked. It was terrible - very little flavor, and a texture like firm tofu. Not mushy like over the hill shrimp, but soft, almost grainy. This was true of the whole package, not just a couple of shrimp.
Live and learn.
