Thanks to Margot, from Effort to Deliciousness, for her pick of Chocolate Fluff-filled Madeleines, found on pages 170-171 of Dorie Greenspan's Baking from My Home to Yours cookbook. You can find the recipe here. Margot makes terrific toffee, just ask Matt, she sent us some with her recipe and I have been answering requests for toffee from Matt ever since. He even calls it Margot's Toffee (don't tell David Lebovitz that, however).
I love Dorie's recipes, I do. Week after week, I am the one who always bakes everything as written figuring Dorie knows way more than I do and I am here to learn from her. That said, the very first recipe that I baked when I joined the TWD group was Dorie's for Madeleines. And it was good, it was very fussy in preparation compared to my It's A Good Thing recipe, and it didn't taste quite as good as It's A Good Thing recipe, but I was happy to have made them.
