Well, did you bring me back any? : )
Elizabeada, you can order the Laduree cookbook from Amazon.fr
My sister has it and it's gorgeous. And yeah, it's in French. No sign of a translation coming out soon. If you want to order from a US bookstore, maybe Kitchen Arts and Letters in NY has it.
http://www.kitchenartsandletters.com/Pierre Herme also had a cookbook translated by Dorrie Greenspan, published by Little, Brown, if I remember correctly. Or maybe Clarkson Potter? I don't know if that one is still in print. I had it at one point, but thought the recipes were so difficult, so I gave it to my mom.
My favorite macaroon recipe, and probably the simplest is Nigella Lawson 's pisatchio macaroon recipe in HOW TO BE A DOMESTIC GODDESS. Once you figure out a basic macaroon recipe, then you can start fiddling around with the fillngs, flavorings until you make a successful knockoff.
