Directions

  1. Pour the the white wine into a stainless steel pot, adding the lemon juice and finely chopped onions. ≈ 3 min
  2. Cook this mixture until it reduces to about 30 ml. Don’t worry if the sauce is too thick; it will thin out when mixed with the butter.
  3. Reduce the heat to low. If you want to thicken your sauce, add the heavy cream at this point, but every traditional French chef would disagree.
  4. Begin by adding cold, cubed butter while whisking vigorously. The sauce should not exceed 95 °C, so turn off the heat and continue whisking. Add 1 or 2 cubes of butter and continue adding until all the butter is incorporated. ≈ 4 min
  5. Season with salt and white pepper, and serve immediately. The sauce can be stored in an airtight container, but this method is not recommended for long-term storage. ≈ 2 min
