This is one of my favorite sauces for grilled seafood, especially swordfish. It is also terrific with salmon, striped bass, halibut, tautog, and other white-fleshed fish suitable for grilling. Think of this recipe as a formula. The ratio of cucumber to the other ingredients is important, but from there you can adapt this sauce to match with different fish or even side dishes. For example, with a Latino or Caribbean dish like Black Beans and Rice, you could substitute fresh lime juice for the lemon juice and add chiles and cilantro. This recipe uses half yogurt and half sour cream, but you could use any combination of the two. Or, for salmon, you might want to use all sour cream, with dill. You could also make a low-calorie sauce using all low-fat yogurt. The first time you make the sauce, if you follow my guidelines but omit the jalapeño and use parsley and chives for the herbs, you will have a basic sauce. After that, you are on your own. The list of possible variations is extensive.
For equipment, you will need a stainless steel (or plastic) strainer.
