Hi Maangchi,
Your website is amazing. I just came back from what was supposed to be a stopover in Seoul that ended up being a highlight of the trip. My friend and I went crazy shopping in the Shinsagae Food Hall.
I bought 2 packs of toasted black soybean and grains powder because some woman made a drink from it and had us taste it. I cant remember though, if I should mix it with milk or with water?
Can you help? Also, are there any other uses for the powder?
Many thanks
ps -- thanks loads for the video on kimbap -- I bought the mold and wrapper when I was there too!
