Make your own tartare sauce to add sprightliness to whole cooked whiting—the homemade sauce has a zest lacking in the bought version.
To make a quick tartare sauce, blend together 2 tablespoons each of sour cream and mayonnaise with 1 teaspoon lemon juice, ½ teaspoon Dijon mustard, 1 tablespoon chopped capers and 4 finely chopped gherkins.
