Donsuemor, Chicago, adds two products to its line of high-end bakery goods. The Nonnette and the Petit Gateau debuted in May at the Sweets & Snacks Expo. The Nonnette is a classic French treat, small in size and full of flavor. It is a bite-sized snack featuring a hint of Meyer lemon ­essence. The Petit Gateau, or “little cake,” is a delicate, bite-sized cake with a touch of orange that adds a surprising pop of flavor.
