I want to have something for breakfast, but when I'm busy even prepping feels like a hassle. Soy milk is perfect for those moments, so this time I'm introducing a powdered type you mix with water yourself — Garu Teacher Taemeogneun Saengduyu Yakkong 99.3 (Garu Teacher 타먹는 생두유 약콩 99.3). You scoop out just what you need and adjust the concentration to your taste, so it's worth a look if you usually like the nutty flavor of beans. :)
What is in Garu Seonsaeng Yakkong 99.3? Korean black soybeans 99.3%, sea salt 0.7%
Garu Teacher's yakkong soy milk is made up of 99.3% Korean black soybean and 0.7% Korean sea salt. Yakkong (약콩) is also known as jwinunikong, or 'rat's eye bean.'
It's a powder finely ground with the skin on, so there's no need to soak or grind beans yourself — you just scoop out as much as you need.
No added sugar, emulsifiers, preservatives, or flavoring, so it's worth a look if you're after soy milk with a simple ingredient list.
That said, no added sugar doesn't mean zero sugar entirely. Based on the nutrition info provided, it's 132kcal, 1.2g sugar, and 13g protein per 30g. Good to keep in mind when deciding how much to drink.
How does it taste? Nutty beans rather than sweetness
Garu Teacher's yakkong soy milk tastes closer to plain soy water than a sweet drink.
With a small amount of sea salt added, the nutty bean flavor comes with a subtle seasoning. If you usually enjoy sweet soy milk, it might feel a bit plain at first, but if you found strong sweetness too much, this plainness might actually suit you well.
With powdered soy milk, the taste and texture also change depending on the amount of water. Try mixing it at the ratio printed on the product first, then adjust the concentration to your taste.
How to mix Garu Seonsaeng soy milk powder in a shaker, and how to store it
The method isn't hard. Add water to the shaker first, then the powder, close the lid, and shake well.
Rather than making it strong from the start, it's easier to mix it well first and then add water little by little to reach the concentration you want.
You can't drink it right away like a finished product, but being able to decide the amount and strength yourself is the appeal of the powdered type.
It comes in a zipper bag, so after use, close the opening properly for storage, and it's good to scoop it out with a dry spoon. Please follow the storage instructions on the packaging.
Mixing the soy milk powder into milk, yogurt and oatmeal
Besides mixing it with water, you can use it in various ways. For a softer taste, mix it into milk; if you want to enjoy it as a spoonable snack, mix a small amount into plain yogurt.
Adding granola or nuts on top gives it some crunch, too, and mixing it into oatmeal adds nuttiness. For breakfast, try pairing a glass of soy milk with fruit or whole-grain bread.
Who Garu Seonsaeng Yakkong 99.3 suits best
Garu Teacher's yakkong soy milk suits people who check where the beans come from and their content ratio, people who like a plain, not-too-sweet taste, and people who want to adjust the concentration themselves.
- People who care about the origin and content ratio of the beans
- People who like a plain, not-too-sweet taste
- People who want to adjust concentration with water amount
It's easy to mix up a glass, and you can use it in yogurt or oatmeal too, so if you're looking for a powdered soy milk to keep at home, start by comparing ingredients and quantity. :)
