Powdered oat drink for breakfast: Garuseonsaeng Oat Drink
Garuseonsaeng Powdered Oat Drink is a 500 g oat powder drink for breakfast or after light exercise in Korea. I mixed it with water, milk, and warm water; it was mild in water and richer with milk, though a little powder sometimes settled at the bottom and I needed a try or two to find my preferred thickness.
