Some recipes are just not helpful.
The wife and I are making Thai shrimp lettuce wraps for dinner. I buy my shrimp frozen from Costco and this recipe calls for cooked chilled shrimp, so I need to defrost, cook, and chill the shrimp during the day before she gets home. So I asked her "hey, just simple salt and pepper to season the shrimp ok?", and she said the recipe was printed in our cookbook.
So I looked it up. It calls for 16-20 pre-cooked jumbo shrimp. It doesn't reference what "jumbo" means, nor an overall weight of what those "jumbo" shrimp are supposed to be. Nor, because it only says this, does it have ANY reference to any sort of seasoning or cooking method for the shrimp--obviously I think most pre-cooked shrimp is steamed, but I know very little about the seasoning.
There is no universal definition of jumbo shrimp. Online it says that it can often refer to 16-20 count and it can also often refer to 21-25 count shrimp. Assuming the midpoints (18 and 23), 16 shrimp could be as much as 0.88 lbs or as little as 0.7 lbs. 20 shrimp could be as much as 1.25 lbs or as little as 0.87 lbs.
I buy the 13-15 count shrimp. None of that puny 16-20 or 21-25 stuff!
Screw it. I'm going to use 1# of shrimp, hit it with a little salt and pepper, and cook it in the wok.
