If Marie Antoinette wanted a frosty cone of shaved ice, she might have turned to Marc Aumont, the executive pastry chef at Gabriel Kreuther and Kreuther Handcrafted Chocolate. His crystalline chocolate shaved ice, worthy of Versailles, comes piled in a coupe or cup (dine in or take out) and glossed with raspberry, mango or praline sauce. Indulge on the spot or carry it out to Bryant Park.
