I've never been a fan of wasabi—it gives me the sensation that my nasal passages are on fire—but if anyone could make it taste good, it'd be master French pastry chef, Pierre Hermé. Wasabi-flavored macarons are a part of his fall pastry line, found at his shops in Paris and Tokyo. He just opened a new shop last month in Paris at 4 rue Cambon, in case Parisians need another reason to get to Pierre Hermé (not that they should).
Can't get to his shops in Paris or Japan? Maybe you can get some help from his recently released macaron recipe book, Macaron. It's available at amazon.fr for €28.41 ($39.22).
