My wife’s niece had her birthday this past weekend, so I baked her a favorite. büche de Noël. Though not quite the season, what a girl loves, a girl loves. In particular, she loves merengue mushrooms. What else? Chocolate? Nope. She does not like it! Go figure. So I flavored it with pistachio rose water and matcha tea buttercream, on a base of a hazelnut sponge cake. Turned out tasty and we had a good time.
