Korean Shrimp Jeon (Egg-Battered Pan-Fried Shrimp Pancake)
Butterflied flat along the belly, the shrimp cook evenly and hold a thin flour-and-egg coat better than whole ones would. The trap with saeu-jeon is color: the coating turns pale gold and the surface turns pink well before the thickest shrimp are opaque at the center. Translucent flesh in the middle means more time in the pan, while firm, opaque shrimp should come out right away so they do not toughen. Lemon wedges on the side add a bright finish.
