I think mayonnaise-and-lemon-juice is a long short story, with some angst and misunderstanding but also humour and ultimately a romantic happy ending. Ideally, it has been written by someone like astolat or nandamai.

Chargilled-with-chili-and-garlic is obviously darkfic with kink, yes. Ideally, it has been written by someone like synecdochic or ivorygates.

ETA: Possibly I am putting too much thought into this.
