Don’t confuse beurre de noisette, which is made with hazelnuts, with beurre noisette. Beurre noisette is butter cooked until it takes on a nutty, butterscotch-like flavor; it contains no other ingredients than butter.
Beurre de noisette is made with hazelnuts, usually about 1 part nuts to 3 parts butter. The hazelnuts should first be toasted in the oven to bring out their flavor. Remove as much of the dark skins as possible by rubbing the hot nuts against each other in a kitchen towel. Grind the nuts with the butter in a food processor for about 5 minutes, stopping when needed to keep the butter from melting. Alternatively, since a food processor can’t produce a perfectly smooth paste, you can substitute unsweetened praline paste for the hazelnuts.
