zagoreti
to burn, but not really. It's only about food, when it goes brown or black on the bottom or edges, and sticks to the vessel. Specially happens when you boil the milk - can't call that burning, can you?
As a passive adjective - zagoreo/la - it denotes a vessel which wasn't properly scrubbed after this happened (possibly more times). In slang it means, by inference, eager for sex after a considerable number of days without it.
