Chef's technique step by step

  1. 1

    Cut the butter up into small pieces and place in a frying-pan.

  2. 2

    Melt the butter over a medium flame, watching carefully.

    Chef's tip

    To keep control of the process, do not turn up the heat too much.

  3. 3

    As the butter melts, the casein (the protein in the milk) will form a white scum on the surface.

    Chef's tip

    You can stir the butter to make sure it does not overheat.

  4. 4

    As it heats up, the butter soon turns an amber colour and gives off a hazelnut fragrance (this is due to the casein caramelising).

    Chef's tip

    You will know when the butter is done just right when it begins to give off a toasted-hazelnut fragrance.

  5. 5

    Immediately add a small piece of fresh butter to slow down the cooking process, then pour the beurre noisette into another container to stop the process completely (otherwise the casein will take on an undesirable black colour).
