Beurre Blanc
Ingredients
&w=3840&q=75){kind=small}
- 2 tbsp shallot – finely minced
- 1/2 cup dry white wine
- 1/4 cup white wine vinegar
- 1 tbsp heavy cream – optional
- 8 ounces unsalted butter – cold, cut into 0.5-inch cubes
- 1/2 tsp fine sea salt
- 1/8 tsp ground white pepper
Instructions
1. Finely mince the shallot.
2. Add it to a small heavy saucepan with the dry white wine and white wine vinegar; bring to a brisk simmer over medium heat and cook until reduced to about 2 tbsp and syrupy, 5–7 minutes.
3. Lower the heat to very low; whisk in the heavy cream (if using) and let it just bubble for 10–15 seconds, then remove the pan from the heat.
4. Off the heat, whisk in the unsalted butter a few cubes at a time, letting each addition nearly melt before adding more; as needed, briefly return the pan to low heat to keep the mixture just warm, and continue 3–5 minutes until the sauce is thick, smooth, and glossy.
5. Season with the fine sea salt and ground white pepper; serve immediately, keeping the sauce warm but below a simmer so the emulsion stays intact.
Beurre blanc is a warm, emulsified butter sauce known for its silky texture and bright, wine-vinegar tang balanced by rich butter. It coats delicately, making it an ideal partner for poached or sautéed fish, shellfish, and tender vegetables like asparagus. The flavor is clean and elegant, with aromatic shallot notes and a gentle peppery finish.
Originating in the Loire Valley around Nantes, beurre blanc is closely tied to local Muscadet wines and seafood traditions. Culinary lore attributes its creation to Clémence Lefeuvre in the early 20th century, where a missed hollandaise allegedly led to this new style of butter emulsion. Over time, it became a cornerstone of French restaurant cuisine and nouvelle cuisine, sometimes called beurre nantais when the shallots are left in the sauce.
