This is a classic mayonnaise-based sauce that we've lightened using a combination of reduced-fat mayonnaise and yogurt. In addition to seafood, the sauce complements cold roast beef, chicken or hard-boiled eggs.
Whisk mayonnaise, yogurt, mustard, lemon juice, anchovy paste and cayenne in a small bowl until smooth. Stir in capers and parsley.
Make Ahead Tip: Cover and refrigerate for up to 4 days.
