Powdered soy milk that mixes in cold water: Garu Seonsaeng Injeolmi

In short

Garu Seonsaeng Injeolmi Powdered Soy Milk is a 500g soy milk powder you mix with water. Two measuring scoops per 180ml of water dissolve well even in cold water, and the roasted Korean soybean flour and unrefined raw sugar give Garu Seonsaeng Injeolmi a nutty taste rather than an artificial sweetness. It is an easy one to keep on hand as a quick breakfast for office workers or a snack for kids who dislike plain milk.

Today I want to recommend Garu Seonsaeng's Injeolmi (rice cake coated in roasted soybean powder) powdered soy milk that you just mix with water.

What kind of brand is Garu Seonsaeng?

Garu Seonsaeng, made by Hyumil, is a brand I only recently discovered — it makes healthy convenience foods based on 100% plant protein, using natural whole ingredients instead of synthetic additives.

Beyond the injeolmi flavor, they also make drinkable raw soy milk powders in white soybean, black soybean, and small black bean varieties — you can tell this is a brand that's really serious about soy milk.

Why I chose Garu Seonsaeng Injeolmi soy milk powder

One reason I often reach for soy milk as a drink is that it works as a meal replacement. My typical office-worker morning is a war between my eyelids and 'just five more minutes of sleep,' so I've repeated the same bad habit for years — skipping breakfast and pouring coffee into an empty stomach at work. The moment I saw Garu Seonsaeng's Injeolmi soy milk, I thought it would be great to keep in the office pantry for breakfast or lunch.

On days when work stress kills my appetite but I still need to get some nutrition in, I often reluctantly reach for something easy to swallow like milk. This product felt like a good fit for those busy times when I don't even have time to go eat, letting me get both taste and nutrition.

On top of that, seeing Garu Seonsaeng's drinkable raw soy milk immediately reminded me of my school days, mixing chocolate powder into plain milk because I hated drinking it straight. I figured kids who dislike white milk would love this injeolmi flavor too, since it's a flavor almost everyone enjoys. Good for office workers as a meal replacement and good for kids as a snack — that's why I chose Garu Seonsaeng's Injeolmi soy milk.

Unboxing and tasting the 500g bag

When I heard it was 500g, I couldn't quite picture how much that would be — turns out it's a mid-range amount, not too much, not too little. Thinking about storage after opening, that felt like the right size. It comes in a zipper bag, so you can just reseal it and keep it in the bag, or transfer it to a separate container.

What I liked about Garu Seonsaeng Injeolmi

1) There's nothing really breakable here, but I appreciated the neat, careful box packaging. A measuring scoop was included too, which was handy for gauging a single serving (2 scoops per 180ml water).

  • 2) Since the reason I drink soy milk isn't really about sweetness or hydration but mostly about meal replacement or nutrition, I care more about what ingredients are used and whether they're safe than about plain sweetness. I liked that it uses real whole ingredients and unrefined raw sugar instead of artificial flavoring or excessive refined sugar.
  • 3) With roasted Korean soybean flour and a soy base, it had a soft, nutty flavor that really tasted like eating real injeolmi rice cake.
  • 4) I assumed a 'drinkable raw soy milk' would need actual milk, but I liked that it's mixed with water instead, and for convenience it's formulated to dissolve well even in cold water.

Is this powdered soy milk worth buying?

That's my look at Garu Seonsaeng's Injeolmi Powdered Soy Milk. It's a healthy snack that dials back artificial sweetness and highlights the natural nuttiness and mild flavor of real ingredients — I'd recommend it as a meal replacement for office workers or as a snack for kids.
