Jeungpyeon (Fermented Makgeolli Rice Cake)
Long counted as a summer treat, jeungpyeon starts with rice flour mixed with unpasteurized makgeolli, a cloudy Korean rice wine, and left to ferment for about an hour before steaming. The cake comes out full of fine air holes with a faint tang and rice-wine aroma, and it breaks apart lightly instead of chewing. In a cool room fermentation slows, and the small bubbles in the batter, not the clock, decide when it is ready.
