Fritter is a method of frying in which the food is coated with whipped egg whites and then deep-fried. A light and fluffy batter characterizes it, and it is fried at a low temperature to prevent excessive browning. In addition to fish and vegetable fritters, fruit fritters are also well-known as desserts.

"Candou," also known as "winged bean," is relatively large in size, measuring about 3 centimeters. Its shape resembles that of a winged beetle. Candou tends to wilt easily and become hard when exposed to air, so it is recommended to remove the outer shell before cooking. Candou is typically blanched or grilled with the outer shell intact before consumption.
