Specific steps:

Corn residue and chopped green beans.

Cleaning corn residue

Boil water in a rice cooker, and add corn residue after the water boils.

Remember to stir halfway to avoid sticking to the pot.

When the corn residue is cooked, the green beans are cooked.

Open the lid and cook slowly until the corn residue is sticky.

Get out of the pot and put it in the bowl.
