On this Jewish holiday, I spent most of the time in the kitchen, which puts me right in step with my foremothers. I was trying out a new recipe for a Passover dessert. These are Coco Thumbprints from Dorie’s Cookies, and they’re an updated version of macaroons filled with chocolate ganache. It took me a couple of batches to get it right. Tonight, I’m bringing this to another Seder and I’m hoping they go over well.
