'buche de noel' on Serious Eats
Making a traditional Bûche de Noël is a lengthy project that requires time and planning. you'll want to make many of the components in advance so they have time to chill: the mushroom meringues, soaker, compote, and pastry cream keep for up to 2 days before use.
Mushroom meringues are usually associated with the traditional French dessert Bûche de Noël, but I like to make them on their own as a creative, delicious, and gluten-free addition to cookie plates during the holidays. This recipe comes from Maida Heatter's Book of Great Desserts.
