Cold Poached Shrimp
You can buy peeled shrimp, but shrimp poached in their shells have more flavor (as do shrimp poached in salt; the water should taste salty). If you’re going to peel the shrimp yourself, as I recommend, it pays to buy larger shrimp and cut down on the work. Go for those in the range of 30 to 40 per pound (sometimes labeled U-40 as in “under 40”), or even larger if the cost is not prohibitive. To subtly improve the flavor of the shrimp, add other seasonings to the poaching liquid—the easiest thing is to grab a handful of pickling mix, which usually contains peppercorns, allspice, bay leaf, and coriander and dill seeds. Throw in a couple of cloves of garlic or a piece of onion if you like.
