Okay kiddo, do you know what beans are? They're little seeds that grow in pods and people eat them in different ways like in soups, salads, or even on their own.
Now, fermented bean paste is basically a tasty sauce that's made from beans. But instead of just cooking the beans and eating them right away, people let them sit for a while in a special container that helps them turn into a paste.
During that time, little tiny creatures called bacteria help the beans break down and turn them into a yummy paste with a strong flavor. It might sound a little weird, but it's a really cool process.
Once the beans turn into a paste, people use it in all sorts of recipes. It adds a really unique, savory taste to food. So next time you're eating something that tastes really delicious and has a mysterious flavor, it might just be fermented bean paste!
