Black bean paste is kind of like a yummy sauce that you can put on food. It's made from black beans, which are small, dark-colored beans that grow in little pods.
To make the paste, someone cooks the black beans in hot water until they get really soft. Then they mash them up until they turn into a sort of soup.
After that, the soupy mixture is left out to dry in the sun or in a warm place until it gets thick and paste-like. Then it's ready to use!
People use black bean paste in lots of different ways. Some people like to spread it on bread or crackers like you might with peanut butter. Others mix it into soups, stir-frys, and other dishes to add flavor.
So, just remember that black bean paste is made from black beans, is used to add flavor to food, and can be spread on things or mixed into dishes. Yum!
