A garlic press is a kitchen utensil to crush garlic
cloves efficiently by forcing them through a grid of small holes, usually with some type of piston. Many garlic presses also have a device with a matching grid of blunt pins to clean out the holes.
Garlic presses present a convenient alternative to mincing garlic with a knife, especially because a clove of garlic can be passed through a sturdy press without even removing its peel. The peel remains in the press while the garlic is extruded out. Some sources also claim that pressing with the peel on makes cleaning the press easier.
