Crush garlic like they do on TV

Take a whole, unpeeled clove of garlic and lay it on a cutting board. Take a broad-bladed knife or cleaver, lay it sideways on the clove and pound it once with your fist. The skin will easily pull away. Continue chopping or crushing as needed.

NB: garlic gives out more or less of its flavour depending on what you do to it. Crushing it releases most of its 'garlicky effect', chopping it slightly less; slicing it less still, and leaving it whole the least of all.
