While I couldn’t pry the recipe out of M. Jaccard when I visited his pastry shop last May, I was fortunate enough to find this wonderful video of him and his son preparing the Amandine in his pastry shop in Switzerland.

I’m hoping to be back in the area soon and maybe I’ll be able to get the recipe next time!
