Pierre Herme currently offers 10 flavours in small macarons. The white one on top is his most infamous classic flavour - white truffle with grilled hazelnuts.
And La Cerise sur le Gateau - the Cherry on the Cake. Hazelnut dacquoise; thin milk chocolate shavings; lightly sweetened whipped cream; milk chocolate ganache; topped with a stemmed, candied cherry on the cake.
Yes, the buches will be gone within the next 24 hours or so - until next year. I hope this provides some consolation - and reassurance.
