Every so often a restaurant shakes up the world of sweets. In this episode we visit three of NYC's game changers, putting a new spin on old favorites. At Dominique Ansel Kitchen time is the secret ingredient: desserts are made to order instead of ahead of time. So the classic French pastry mille-feuille is freshly piped with thick, luscious pastry cream, and the Yuzu Lemon Tart is filled to the brim with freshly-blended citrusy yuzu-lemon curd. At Good Batch, a passion for cookies has evolved into groundbreaking ice cream sandwiches, like the deconstructed candy bar called the Macaroon Ice Cream Sandwich: creamy vanilla ice cream sandwiched between coconut almond macaroons and layered with chocolate caramel and almonds. And the frozen desserts at Snow Days make childhood dreams come true: feathery shavings of flavored frozen creams in inventive flavor combinations, such as the Yeti Food: blueberry and chocolate sandwich-cookie flavored shaved cream topped with ripe bananas, crushed waffle cones and blueberry puree.
