1, soak the big slag one night in advance, as shown in the figure, which is easy to cook.

Kidney beans are the same as big scorpions. Soak the kidney beans in advance after washing, so that they are fully soaked and easy to digest.

3. Add the soaked kidney beans and ballast into the pressure cooker, about two fingers high (you can add a little alkaline noodles to cook porridge, which tastes good and doesn't like to ignore it).

4. Cover the high-pressure pot cover and air valve. After the fire cuts off the steam, turn it to a small fire for 20 minutes.

Finally, don't open the lid immediately after the fire. It will be softer after stewing for a while. Just eat it directly into the bowl.
