One of the great qualities of Greek yogurt is the ease with which one can use it to replace or reduce the quantity of mayonnaise used. This is a classic example.
1 cup (240 ml) Greek yogurt, preferably full-fat
½ cup (120 ml) good-quality mayonnaise
3 tablespoons minced cornichon pickles
1 tablespoon chopped capers
2 teaspoons Dijon, Greek, or other pungent mustard
Grated zest of 1 lemon
Juice of ½ to 1 lemon, strained
Salt and freshly ground black pepper
Whisk together the Greek yogurt and mayonnaise in a small bowl. Using a spatula, mix in the cornichons, capers, mustard, and lemon zest. Taste and add lemon juice, salt, and pepper to taste.
