Nutrition (per serving)
Method
Pour the fish stock into a small saucepan and bring to a gentle simmer around 85°C/185°F. Keep warm over very low heat.
In a medium saucepan, melt the unsalted butter over medium-low heat until it foams but does not take on any color.
Whisk the sifted all-purpose flour into the melted butter to form a smooth paste, creating the roux.
Cook the roux gently over medium-low heat for 2 to 3 minutes, stirring constantly. It should smell toasted like pie crust but remain pale yellow in color.
Gradually ladle the hot fish stock into the hot roux in three additions. Whisk vigorously after each addition to ensure a perfectly smooth, lump-free base before adding more liquid.
Once all the stock is incorporated, bring the mixture to a gentle boil to activate the thickening properties of the flour.
Reduce the heat to the lowest setting and simmer gently for 15 minutes. Use a ladle to continuously skim off any foam or impurities that rise to the surface.
Remove from heat. Season with fine sea salt and white pepper to taste. If any trace lumps remain, strain through a fine mesh sieve before using or storing.
Chef's Notes
- Always match the temperature of your ingredients: hot stock into a warm roux prevents temperature shock that leads to clumping.
- When a recipe calls for reducing a veloute, hold back on initial seasoning. As water evaporates, the salt concentration intensifies rapidly.
- A proper veloute should perfectly coat the back of a spoon (nappe) and leave a clean line when you run your finger through it.
- To prevent a skin from forming while cooling a veloute, gently glide a cube of cold butter over the hot surface to create a protective lipid layer.
Storage
Refrigerator: 3 days — Cover surface directly with plastic wrap or a buttered cartouche to prevent a skin from forming.
Freezer: 1 month — May separate slightly upon thawing. Whisk vigorously over gentle heat to re-emulsify.
Reheating: Reheat gently over low heat, whisking constantly. If the sauce becomes too thick, thin with a splash of hot fish stock.
