Dough is basically what we use to make bread, pizza, and lots of yummy baked goodies! Imagine you're making a sandcastle at the beach. You take some sand and add water to it, then mix it all together until it's a big clump. Dough is kinda like that!
But instead of sand and water, we use special kinds of flour, yeast, water, and maybe some other things like sugar or salt. Mixing everything together takes a bit of work - we have to knead the dough (that means mushing and squishing it with our fists) until it turns into a soft, stretchy ball. This is important because it helps the dough grow and become fluffy when it bakes.
Once we have our dough, we can use it to make all sorts of things! We can roll it out thin and make pizza crust, or shape it into loaves for bread. We can add yummy things like cheese or chocolate chips to make it even better. Then we put it in the oven and wait for it to bake! When it's all done, we have delicious, warm, fresh-baked treats to enjoy!
