Do it yourself, it's simple! Since I made it myself, I would never buy anything outside. Too sweet, the color is black. God knows what's in it. Soak adzuki beans in boiling water for two hours, take them out and put them in a pressure cooker for half an hour, then take them out and break them with a food processor. It will be delicate and the skin will not be wasted. Put sesame oil in the wOK (I put butter in it, and my family says I'm not used to the smell), fry it (it's very laborious, you can exercise your arms, of course, you can ask your husband to do it for you, and it doesn't smell good without work), and it's ok. I didn't buy a cooking machine when I first made it. My husband and I spent six hours grinding it with gauze. It tastes better, but it's too much trouble.
