Beurre Blanc Broken
Beurre blanc that's broken into a greasy puddle can often be rescued with a new reduction and patient re-emulsification — here's how to save it.

The fix
Tap a step to check it off.
- 1 In a clean saucepan, reduce 2 tablespoons white wine and 1 tablespoon vinegar with a minced shallot to 1 tablespoon
- 2 Add 1 tablespoon heavy cream and bring to a simmer — the cream provides a stable emulsifying base
- 3 Over very low heat, whisk in the broken beurre blanc tablespoon by tablespoon as if adding new butter — it often re-emulsifies into the new base
- 4 Keep the pan at 140–160°F maximum — above this temperature the emulsion breaks irreversibly
If it's still wrong
- Use the broken beurre blanc as a finishing butter on steaks or fish — melted clarified butter with white wine flavor is still delicious even if unemulsified.
- Blend the broken sauce with an immersion blender vigorously — mechanical emulsification can temporarily rescue a broken sauce, though it will be less stable.
Prevent next time
- Maintain the sauce at 140–160°F at all times — use the lowest possible burner or a double boiler for holding.
- Add 1 tablespoon heavy cream to the reduction before adding butter — the extra protein makes the emulsion significantly more stable.
