Usu (Mortar)

Usu (mortar) is a tool that looks like a bowl and is used to grind things into a powder or paste. It is usually made of a hard material like stone or metal. You put what you want to grind inside the bowl and then use a tool called a pestle to crush and grind it until it becomes the texture you want. People use usu (mortar) for many things, like crushing spices to make a yummy meal, grinding up medicine to create a potion, or making a paste to fix something broken. It's like using a giant spoon to make something smaller and easier to use.
