Macerate

Macerate means to soften something or break it up by soaking it in liquid.

You can soak bread in milk and macerate it with a fork or you can macerate potato in gravy.

There is a machine called a macerator which can be attached to sinks and toilets that mash all the waste into a liquid that can be forced down narrower sewage pipes than would ususally be used. Eee-yew!
