In this edition of "Food Skills," we head to Old Tbilisi Garden in Greenwich Village, one of the few restaurants in New York City to serve traditional Georgian cuisine. The highlight of the menu is a bread-shaped boat of cheese and egg yolk called khachapuri adjaruli. To make the classic dish, a mound of slightly sour sulguni is stuffed inside butter-brushed dough, before being left to brown and bubble in the oven.
