Revolutionize Bland Fish Dishes with This Versatile Sauce – Works with Meat Too!

Even if you’re a fan of seafood, it’s hard to deny that some ocean fare is painfully bland. No matter how much you season or bread them, sometimes it just doesn’t cut it. Thankfully, there’s a traditional French sauce so bursting with flavor that it can transform even the most tasteless fish. Originally a companion for red meats, at the Parisian bistro Les Capucines, it’s served over a whole sea bass à la Colbert. Some even pair it with scallops. You’ll find that it adds a bistro flair to even the blandest white fish…

What’s this magical sauce called? Choron sauce, named after the French chef who created it by accident while making béarnaise sauce. Rich and aromatic, it consists of a béarnaise base with shallots and tarragon, enhanced with crushed tomatoes. “The goal is to achieve an emulsified sauce: coating texture, buttery taste, finished with tomato,” explains Chef Michel Dumas on his website. He advises following his expert tips to make it just right.

For the aromatic reduction of Choron sauce, you’ll need white wine, vinegar, shallots, and tarragon. For the sabayon, you’ll need eggs, water, and unsalted butter, to which you’ll add a tomato.

• 2 tbsp. white wine vinegar
• 2 tbsp. dry white wine
• 1 tbsp. chopped shallot
• 1 tsp. dried tarragon or 1 tbsp. fresh tarragon
• 15 ml water
• 2 egg yolks
• 150 g unsalted melted butter (about 45°C)
• 1 tbsp. water (only if the reduction is very concentrated)
• Salt, pepper, and a pinch of Cayenne pepper (optional)
• 1 tomato

1. In a small saucepan, simmer the vinegar, white wine, finely chopped shallot, chopped tarragon, and water. Let it reduce slowly until you have about 1 tbsp. of concentrated liquid. This process should take between 5 and 8 minutes, according to the chef.

2. Strain this aromatic reduction through a sieve, pressing lightly on the shallot, then set aside.

3. In a saucepan off the heat, whisk the egg yolks, the strained aromatic reduction, and a bit more water if the mixture is too concentrated.

4. Place over low heat and continue to whisk, reaching about 45°C. Be careful not to exceed 50°C to avoid scrambling the eggs. The sabayon is ready when it slightly foams and thickens.

5. Gradually add the melted butter (at 45°C), whisking continuously. Once the sauce becomes glossy, you can pour in a thin stream. If the mixture is too thick, thin it with 1 tsp. of warm water and whisk well. Season with salt, pepper, and Cayenne pepper (optional).

6. Gently fold in the tomato previously blanched and diced into very fine brunoise. To do this, score a cross on the bottom and blanch the tomato for 10 seconds in boiling water. Then peel, deseed, and dice it finely.

Now all that’s left is to drape this generous sauce over your fish fillet and enjoy. Still warm, it will spread the aromas of tarragon, tomato, and shallots throughout your dining room…
