Okay kiddo, so you know how when you make soup or noodles or other yummy things, you usually use water? Well, in Japan, they have a special kind of water called dashi.
But really, it's not just plain water, it's like a magic water that makes your food taste super good. That's because dashi is made by boiling special ingredients together. Those ingredients are usually dried fish flakes, kombu (a type of seaweed), or both.
When you boil these ingredients in water, their special flavors and nutrients mix together to make a really flavorful liquid. You can use dashi to make all kinds of Japanese food taste amazing, like miso soup, noodle soup, and even dipping sauces.
So next time you see the word "dashi" on a menu, know that it means something special that is going to make your food taste really, really good.
