    Time: PT15M

    Temperature: Medium heat

    Time: PT30M

    In a bowl, whisk 4 egg yolks with 80 g sugar until pale.

    Time: PT5M

  16. Cook the bavaroise

    Time: PT10M

    Temperature: Medium heat

    Time: PT5M

  21. Assemble the log – first layer

    Pour half of the vanilla bavaroise into the mold, smooth. Unwrap the frozen caramel mousse, place it in the centre, then lightly cover with bavaroise to make it adhere.
