Sauces

Monter au Beurre

French · to mount with butter

Monter au Beurre

Whisking cold butter, cube by cube, into a finished sauce off the heat until it turns glossy and full-bodied.

Why It Matters

The butter emulsifies rather than melts, giving the sauce a velvet texture and rounded finish. It is the quiet final step behind nearly every sauce served under a star.

How to do it

  1. 1

    Prepare your sauce base.

  2. 2

    Remove the pan from the burner.

  3. 3

    Add cubes of cold, cubed butter.

  4. 4

    Whisk vigorously until melted.

  5. 5

    Incorporate until the sauce looks glossy.

Common mistakes

  1. ✕

    Adding butter over heat breaks the sauce, so remove from fire first.

  2. ✕

    Using soft butter results in thin sauce, so use firm cold cubes.

  3. ✕

    Adding too much butter creates greasiness, so incorporate one piece at a time.
