Alioli
A thick garlic sauce, its name literally meaning garlic and oil, made by emulsifying crushed garlic into olive oil, often with egg yolk added for a more stable, mayonnaise-like texture.

Where it comes from
The oldest versions from Catalonia and Valencia use only garlic and oil, pounded by hand in a mortar. Egg yolk is a later, easier addition that many purists still consider a different sauce entirely.
What cooks argue about
The lasting technical fight is whether alioli should contain egg at all: the traditional version is garlic emulsified straight into oil by hand, notoriously hard to stabilize, against the egg-added version most restaurants serve.
Versions
Nobody has published a alioli here yet. When somebody cooks one from a video and publishes it, their version appears in this list, with a link back to the original.
