Churchkhela is made in autumn at grape-harvest time, when fresh grape must is boiled down with flour into the thick tatara the strings are dipped in.
Churchkhela is made by threading walnuts or hazelnuts onto a string, then dipping the strand again and again into thickened grape juice, called tatara, until it builds into a firm, candle-shaped candy. Rows of the deep-red and amber strands hang from market stalls across Georgia, sold by length and eaten as a chewy snack.
