The jumbo bags in the supermarket just simply do not compare to the fresh, flavor-packed marshmallows by chef Sherry Blockinger. “The vanilla tastes fresher,” says Blockinger. “But the big difference comes in the texture.” Topped with sparkling sugar, the bite size treats deliver a satisfying crunch that gives way to a sweet, doughy inside. And the flavor list will make your mouth water: vanilla, chocolate, raspberry, peanut butter, bourbon vanilla, Irish coffee, cosmo and dark rum. Blockinger recommends dropping them into a cup of coffee or hot chocolate, but we like to nibble them on their own. Get it: Sherry B Dessert Studio, 65 King Street, Chappaqua. 914-238-8300.
