Fresh off his turn fashioning hundreds of mini-doughnuts for the Met Gala last week, Mark Isreal, the owner of Doughnut Plant, turned to what was next on his calendar: Mother’s Day. He has created big yeast “Doughflowers” shaped like roses and available in a choice of glazes: strawberry, made from fresh berries; rose, richly perfumed with rose water and crushed edible petals; and Italian blood orange, sweet and tart with orange blossom water. They will be sold indefinitely starting Wednesday at his shops on the Lower East Side and in Chelsea in Manhattan, and in Long Island City, Queens, and Prospect Heights, Brooklyn: Doughflowers, $5 each, Doughnut Plant stores, doughnutplant.com.
