Ingredienser
Fremgangsmåte
- Reduce white wine, vinegar and onion until there is about 3 tbs of liquid
- Whisk down butter, a little at a time, making sure that the sauce does not boil when you whip down the butter, I try to lie down around 90 degrees.
- Taste with salt and add any other goodies you want to have in the sauce (roe and chives are good)
