Inspired by her Jewish family heritage, Susan Herlands opened My Mother's Delicacies Inc. in 1988 to share her grandmother's respected rugelach recipe and other traditional treats that are certified kosher dairy. Shoppers can peruse an assortment of the coveted, hand-rolled rugelach ($14.99/lb.), a crescent- or square-shaped pastry crafted using a buttery, flaky, cream-cheese-infused crust and speckled with cinnamon, sugar, or nuts. A pound of Hungarian hand-rolled kipfel cookies ($14.99) bubbles over with raspberry, walnut, or apricot fillings, and a small tin of black and white cookies ($21.95) dazzles dessert lovers with a duochromatic treat as decadent as snacking on a 1920s film star. The shop sells pastries individually and by the pound as well as platters and gift towers sizeable enough for parties or a high tea with longtime frenemy Betty Crocker.
