Ingredients

  • 2 Tbsp. tarragon or cider vinegar
  • 2 Tbsp. Dijon mustard
  • 1 tsp. dried tarragon or 1 Tbsp. fresh tarragon
  • 1/4 cup plus 2 Tbsp. plain yogurt
  • 1/4 cup mayonnaise

Instructions

  1. Mix tarragon or cider vinegar, Dijon mustard, dried or fresh tarragon, plain yogurt, and mayonnaise until well blended.
  2. Put a spoonful of the sauce on top of cooked fish.

Tips & Substitutions

For a creamier texture, consider using Greek yogurt instead of plain yogurt. If you want a bit of heat, add a pinch of cayenne pepper. Fresh tarragon adds a brighter flavor, but dried tarragon works well if that's what you have on hand. This sauce also complements grilled vegetables, making it a versatile option for your meals. For a lighter version, swap mayonnaise with more yogurt.

Serving Suggestions

This Tarragon Mustard Sauce pairs beautifully with grilled or baked fish such as salmon or cod. Serve it alongside a fresh salad or steamed vegetables for a complete meal. It also works well as a dip for seafood appetizers. Consider serving it with a side of Cream Puffs for a delightful contrast in flavors.

Storage & Reheating

Store any leftover sauce in an airtight container in the refrigerator for up to 3 days. Before using, give it a good stir as separation may occur. Reheat gently in a saucepan over low heat if desired, but it's often best served cold or at room temperature, especially on fish.
