Garusenssaeng Tamogneun Saengdu-yu Seoritae unsweetened soybean milk product

Why I picked black soybean milk as a diet breakfast replacement

Garu Seonsaeng (Garu Seonsaeng) Tamogneun Saengdu-yu Seoritae is an unsweetened soybean milk powder I found while looking for a breakfast replacement on my diet. As a dieter I worry about sugar, but this black soybean milk was mild, nutty and so delicious.

Keeping up with a diet plan and still not skipping breakfast is harder than I expected. Getting ready for work, I rush around and breakfast always ends up last, and grabbing bread or cereal, which are high in calories, felt uncomfortable. So I spent a while looking for something light to use as a meal replacement, and what I found was Garu Seonsaeng's unsweetened black soybean milk powder!! I'll give you my honest review haha

What comes with Garusenssaeng unsweetened black soybean milk powder

What kind of product is this soybean milk powder?

Garu Seonsaeng black soybean milk is a powdered fresh soybean milk that you stir into water. It's amazing how, just by dissolving it in water, you get the taste of freshly ground soy milk.

Since it's a powder, the shelf life is long too, and you can keep it for nearly a year, which takes a lot of pressure off when you're managing a diet. hahaha

Ingredients: 99.3% domestic black soybeans, 0.7% sun-dried sea salt

Ingredients and sugar content of Garu Seonsaeng black soybean milk

The ingredients are just 99.3% domestic black soybeans (seoritae) and 0.7% sun-dried sea salt...! With no other additives, it feels clean and easy to drink while watching your diet, and since it's unsweetened, you can adjust the sweetness to your own taste, which is a big plus.

Soy milk comes down to personal taste, and the thing I worry about most is sugar! I prefer products without sugar, and since this one is clearly described as unsweetened, I could drink it with peace of mind, and I could recommend it comfortably to friends around me who are on a diet or dieting after giving birth haha

Garusenssaeng black soybean milk dissolved without clumps

I was surprised that it dissolved smoothly without clumps, even without a whisk or blender. Powders usually clump and you end up chewing lumps in one sip haha. And if a powder doesn't dissolve well, it's a hassle to take along, so you stop reaching for it, right? But Garu Seonsaeng's unsweetened black soybean milk dissolves well even in cold water, so I was very satisfied :)

Ways to use it: milk, honey, kongguksu and matcha latte

When I want Garu Seonsaeng black soybean milk richer, I mix it into milk instead of water, and adding a spoonful or two of honey makes it even nuttier, easily good enough to stand in for a meal.

Beyond just mixing it, it's quite versatile! My husband and I have been putting it to good use haha. It works as a base for kongguksu (cold soy milk noodles), a light sprinkle on yogurt adds nuttiness, and mixed with matcha powder I had at home as a latte, it tastes good enough to rival a café.

How does Garu Seonsaeng black soybean milk taste? Is it beany?

Even though it's a powder, Garu Seonsaeng black soybean milk keeps the thick, rich flavor of fresh soybean juice. It's definitely nutty and clean with no beany taste, so I think even people put off by the typical soy milk smell could drink it without trouble.

When you're managing your diet and eat the same flavor every day, you get tired of it fast, but using it in these different ways, I think I keep reaching for it. For anyone who wants to grab a light meal on a busy morning as part of a diet plan, I recommend Garu Seonsaeng's unsweetened black soybean milk.
