If I were in Paris, I would probably have an impossible decision to make if I were to buy only one Bûche de Noël since almost every patisserie makes a Buche de Noel. Sadly, I won't be in Paris, but if you are, here are two outstanding places.
There are beautiful Bûches de Noël by Pierre Herme (Paris). One of the Bûche de Noël is a Chuao Chocolate Buche with Cherry Accents and another is a Buche with chocolate and caramel. Alexis Mabille has created a couture Bûche de Noël for Chocolaterie Angelina. Mabille put his stamp on the traditional yule log with the pastry chef Sebastian Bauer, opting for a heart of creamy chestnuts, candied apple and a confit of yuzu and lime surrounded by milk-chocolate ganache and crisp pecans. Mabille’s bûche is not a log, but a "Cocoa" Chanel bag: quilted and studded with edible silver buttons, topped with Mabille’s signature silver bow. And, almost every patisserie has its own version.
But, since I'm located in the San Francisco Bay Area, I thought I'd post several (but definitely not all) bakeries in the area that make Buches de Noel. Get your orders in now.
