Buying advice
1) Reduce shallots, white wine, and vinegar by two-thirds. 2) Whisk in cold butter, cube by cube, off heat. 3) Season with salt, white pepper, and lemon. 4) Serve immediately over sous vide salmon or cod (122°F). 5) Keep warm, not hot — the sauce breaks above 140°F.
FAQ
What's the ratio?
About 1 stick butter per 1/4 cup reduction — classic proportions.
Why does my beurre blanc break?
It got too hot — keep it warm, not boiling, and whisk constantly.
What fish pairs best?
Sous vide salmon or cod at 122°F — the silky sauce meets silky fish.
