Step 3

Almost all shrimp are frozen before sale. So unless you’re in a hurry, you might as well buy them frozen and defrost them yourself; this will guarantee you that they are defrosted just before you cook them, therefore retaining peak quality.

Step 4

There are no universal standards for shrimp size; large and medium don’t mean much. Therefore, it pays to learn to judge shrimp size by the number per pound, as retailers do. Shrimp labeled 16/20, for example, contain sixteen to twenty per pound; those labeled U-20 require fewer (under) twenty to make a pound. Shrimp from fifteen to about thirty per pound usually give the best combination of flavor, ease (peeling tiny shrimp is a nuisance), and value (really big shrimp usually cost more than $15 a pound).

Step 5

On deveining: I don’t. You can, if you like, but it’s a thankless task, and there isn’t one person in a hundred who could blind-taste the difference between shrimp that have and have not been deveined.
