There is a must-drink drink in Korean holidays for a long time. It's "Sikhye".
Sweet and savory Sikhye is usually eaten with thin ice in hot summer.
Sikhye is believed to aid digestion, it contains dietary fiber and anti-oxidants. It was regularly served to royalty after meals to help digestion.
Drinking a bowl of sweet and cool Sikhye after a hearty meal during holidays and feasts is good for dessert and is helpful for digestion. Sikhye is simple in materials and easy to make, but it takes a lot of time.
