Butterscotch is a sweet flavor that tastes kind of like caramel. It's made by cooking brown sugar and butter together until it turns brown and gooey. Some people add cream or vanilla to give it a creamier taste.
Imagine you have a bunch of little brown sugar granules and some butter. If you put them together in a pot and heat them up, the sugar will start to melt into a syrup and mix with the butter. This is what makes butterscotch!
You might have tasted it before in candy or ice cream. People usually really like the taste because it's so sweet and delicious. But remember, even though it's yummy, you shouldn't eat too much of it because it's not good for your teeth or your tummy!
