It's not authentic, but it's the only simple way I can find.
Step1:I didn't take a picture because I wanted to make purple potato tea towel and there was no bean paste in it, so I remembered to make bean paste myself.
Step2:Officially. Soak the green beans in the water first. Make sure to soak them overnight.
Step3:Then remove the mung bean skin. I just rub and rub all the time. After removing most of them, I will carefully pick out the green beans without peeling. Then it becomes a basin of peeled green beans.
Step4:Put the mungbean in the water and cook until it's soft. It's very soft and loose. It seems that there is another way to steam. But I overcooked it. After all, it's the first time. Forgive me.
Step5:Drain the mung bean. Then scatter it. A friend with a cooking machine can put it in and break it up. It's like mud. Remove and set aside.
Step6:The last step is to put a little oil in the pot, put the mashed mungbean, add sugar and fry until dry. Don't paste the pot.
Cooking tips:Less oil. Mung beans must be peeled. The picture is a picture of purple potato tea towel wring. Inside is the bean paste made by myself. Excuse me. Ha ha, there are skills in making delicious dishes.
