Sake kasu

Okay, so you know how sometimes grown-ups drink a special drink called sake? Well, when they make sake, they use something called sake kasu!

Sake kasu is the leftover bits from making sake. It kind of looks like a paste or a thick batter, and it might even smell a little bit like sake too!

But why do people keep the leftover bits instead of just throwing them away? Well, it turns out that sake kasu is really useful in the kitchen!

First of all, some people like to eat sake kasu as a snack. They might spread it on crackers or bread, or mix it with soy sauce and use it to dip vegetables in.

But that's not all! Sake kasu is also used as a marinade. That means that if you put meat or fish in sake kasu and leave it there for a little while, it will absorb the flavor and become really tasty.

And finally, sake kasu can be used to make soup! You just mix it with some water or broth and heat it up, and you'll have a warm and delicious soup that tastes a little bit like sake.

So there you have it, sake kasu is the leftover bits from making sake, and it's really useful in the kitchen for snacks, marinades, and soup!
