Fish Vinaigrette: A Taste of Summer by the Sea

My grandmother, a true coastal matriarch, had a way with seafood that I’ve always envied. Her fish vinaigrette wasn’t just a dish; it was a summertime ritual. I remember sunny afternoons in her breezy kitchen, the scent of lemon and tarragon mingling with the salty sea air, as she carefully layered the delicate poached fish with her vibrant, tangy vinaigrette. Each bite was a burst of sunshine and the ocean’s bounty, a memory I cherish and strive to recreate in my own kitchen. This recipe is my attempt to capture that magic.

Ingredients

• 3 cups water
• 1/4 cup tarragon vinegar
• 1/4 cup lemon juice
• 6 peppercorns
• 1 bay leaf
• 2 lbs haddock or whiting fish fillets, skinned and boned
• 3/4 cup olive oil
• 3 tablespoons tarragon vinegar
• 3 tablespoons lemon juice
• 1/2 lemon, zest of, grated
• 2 tablespoons onions, diced very fine
• 1 tablespoon capers
• 2 tablespoons fresh parsley
• 1 teaspoon fresh tarragon or 1/2 teaspoon dried tarragon
• 1/2 teaspoon salt
• 1/4 teaspoon pepper

Equipment Needed

• Large skillet
• Jar with a lid
• Bowl
• Knife
• Cutting board
• Zester
• Measuring cups and spoons

Instructions

1. In a large skillet, combine the water, 1/4 cup tarragon vinegar, 1/4 cup lemon juice, peppercorns, and bay leaf.
2. Heat the mixture to just below boiling point. You want a gentle simmer, not a rolling boil. This ensures the fish poaches evenly and remains tender.
3. Add the fish fillets to the simmering liquid.
4. Poach the fish for 5-7 minutes until done, turning once halfway through. The fish is done when it flakes easily with a fork. Be careful not to overcook, as this will make the fish dry. Remember to keep the liquid at a simmer; do not let it boil.
5. Drain the poached fish and cool completely. Discard the bay leaf and peppercorns. These have imparted their flavor to the poaching liquid, so their job is done.
6. While the fish is cooling, prepare the vinaigrette dressing.
7. In a jar with a lid, combine the olive oil, 3 tablespoons tarragon vinegar, 3 tablespoons lemon juice, lemon zest, diced onion, capers, parsley, tarragon, salt, and pepper.
8. Shake vigorously until the dressing is well combined and emulsified. This may take a minute or two. The vinaigrette should appear slightly thickened and cloudy.
9. Once the fish is cooled, break it into bite-sized pieces and place in a bowl.
10. Pour the vinaigrette dressing over the fish, ensuring all pieces are well coated.
11. Cover the bowl tightly and refrigerate for at least 2-4 hours, or even overnight. This allows the flavors to meld together beautifully. The longer it sits, the more flavorful it becomes.
12. Serve chilled.

Expert Tips & Tricks

• Don’t Overcook the Fish: The key to a delicious fish vinaigrette is perfectly cooked fish. Overcooked fish will be dry and rubbery. Aim for just cooked through, where it flakes easily.
• Use Quality Olive Oil: Since olive oil is a prominent flavor in the vinaigrette, use a good quality extra virgin olive oil for the best taste.
• Finely Dice the Onions: Finely diced onions will blend into the vinaigrette and provide a subtle background flavor without being overpowering.
• Make it Ahead: This dish is perfect for making ahead of time. In fact, it tastes even better after it has had time to marinate in the refrigerator for a few hours or even overnight.
• Adjust the Acidity: Taste the vinaigrette before pouring it over the fish. If it is too tart, add a touch more olive oil. If it needs more zing, add a squeeze of lemon juice.
• Infuse the Olive Oil: For an extra layer of flavor, gently heat the olive oil with a clove of crushed garlic for a few minutes before making the vinaigrette. Discard the garlic before using the oil.
• Fresh Herbs are Key: Using fresh herbs, especially tarragon and parsley, will elevate the flavor of the vinaigrette. If you only have dried herbs on hand, use half the amount.

Serving & Storage Suggestions

Serve this fish vinaigrette chilled on a bed of crisp salad greens, garnished with tomato wedges or cucumber slices for a refreshing presentation. It’s also delicious served with baby new potatoes and steamed green beans for a complete meal.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. While the vinaigrette will help preserve the fish, it’s best to consume it within a couple of days for optimal flavor and texture. Do not freeze this dish, as freezing will affect the texture of the fish.
