What is Garu Seonsaeng Injeolmi Drinkable Soy Milk Powder?

Garu Seonsaeng's Injeolmi Drinkable Soy Milk Powder is a 500g plant-based protein powder made from Korean soybean flour. I've been working out and taking protein supplements while dieting lately, and while looking for a healthier protein option, I came across this injeolmi (sweet rice cake coated in roasted soybean flour) powder that also works great as a kids' snack, so I wanted to share it!!!

It's made from Korean soybean flour so you can trust what's in it, and it dissolves really well even in cold water!!!

Garu Seonsaeng review event announcement

Injeolmi Drinkable Soy Milk Powder, made with Korean soybean flour, 500g of plant-based protein. If you like soybean powder coating, this one's for you~!!! I always buy the soybean-coated rice cakes at the tteok shop, so an injeolmi-flavored soy milk had me pretty excited. It's 100% plant-based, made only with unrefined raw sugar, sun-dried salt, and Korean soybeans — real. raw. soy. milk.

Order before 2pm and it ships same day, plus one scoop is included with every package. It's not a flavor imitated with flavoring — the roasted Korean soybean flour combined with the bean-based nutty flavor gives it a rich, deep taste!!!

The expiration date is May 26, 2027, so plenty of time, and the scoop has a nice round handle that's comfortable to grip.

How to mix it: 180ml water, 2 scoops, no added sweetener

I mixed the Injeolmi Drinkable Soy Milk Powder at a ratio of 180ml water + 2 scoops, 30g. Since it has 7% sugar content, the natural flavor already tastes sweet, so I didn't add honey or any other sweetener! I also tried mixing it with misugaru (roasted grain powder) I had at home, and the sweetness level felt just right~

The moment I opened it, the nutty, sweet scent of injeolmi filled the air. I was curious whether it would really dissolve smoothly in water, and — does it really turn into soy milk with just water?? It does, because it contains raw soy milk powder.

Does Garu Seonsaeng's injeolmi powder really dissolve in cold water?

Yes!!!! With the Injeolmi Drinkable Soy Milk Powder, I liked that I didn't have to shake it hard — but just in case, I put it in a tumbler and shook it, and even a little mixing dissolved it completely, making it easy to drink.

A subtle nutty soybean flour scent rose up, and I could taste the toasty, sweet, yet clean flavor unique to injeolmi! The nutty flavor of the soybean itself is at the center so it's never overwhelming, and since the powder dissolves so well, it went down smoothly too.

As a kids' snack and a breakfast substitute with milk

So the kids ate it up happily too. I was satisfied that I could give them just the healthy flavor without any added sweetness — this injeolmi powder.

Especially when mixed with milk, the nuttiness deepens and the injeolmi soybean flour flavor comes through even more, making it a great breakfast substitute!

I packed it to take out and drink while the kids played outside, and with tteok (rice cake) the kids love — Gijang tteok, haha — we dipped it right into the injeolmi powder, haha, and it was so nutty!

Dipping the chewy rice cake into the injeolmi powder really brings out the nuttiness — the subtly sweet rice cake meets the toasty soybean powder, and the clean, nutty injeolmi flavor comes through perfectly, making it a combo you keep reaching for haha.

Who Garu Seonsaeng Injeolmi soy milk powder suits best

With its distinctly toasty, nutty injeolmi flavor coming through so clearly, I think this would suit people who don't prefer overly intense or heavily sweetened flavors!! It dissolves well even in cold water so it's easy to carry around, and when I went to work out, I put just the powder in a tumbler and mixed it with water at the gym~!! Next time I want to try the mugwort and black sesame flavors too!!!
