'All That Crumbs Allow' by Michelle Marek and Camilla Wynne is a culinary exploration of breadcrumbs, presenting 45 diverse recipes that celebrate this versatile ingredient. The authors, both experienced in pastry, offer unique takes on traditional dishes, such as a breadcrumb frangipane for croissants and sweet cheese dumplings enhanced with buttery crumbs. The book includes a comprehensive guide on how to make and store breadcrumbs, humorously addressing the absurdity of purchasing them. Among the sweet recipes are breadcrumb-glazed doughnuts and a rhubarb cardamom breadcrumb cake, while savory options include a detailed schnitzel recipe and roasted potatoes with buttery crumbs. The final chapter features contributions from friends, reinforcing the idea that breadcrumbs should be embraced and shared. Marek and Wynne invite readers to follow a trail of breadcrumbs to discover culinary delights.
