4 unpeeled garlic cloves
½ ts salt

Remove the papery skins, sprinkle the garlic with the salt and work into a smooth paste using the knife blade.

Aioli, from the Provençal Occitan alhòli, or from the Catalan allioli is a garlic mayonnaise, a traditional sauce made of garlic, olive oil, and (typically) egg. The name comes from Provençal alh + òli, something like like garlic & oil. It is served in a wide region, as far as Malta, served with tomatoes, or in North-West Italy, with potatoes.
Try a quick Provençal version.
