Ingredient

Aubergine

A sponge for fat, which is either the point or the problem depending on the dish. Modern varieties are not bitter, so the traditional salting step is now about collapsing the flesh so it absorbs less oil, not about drawing out bitterness.

Sourcing
Middle Eastern and South Asian grocers carry the small and slender varieties that suit stuffing and quick frying far better than the standard large globe.
Varieties
Globe, Graffiti, Japanese, Thai green, White
Quality cues
Glossy, taut skin and heavy for its size. A dull skin, or flesh that stays dented when you press it, means it is old and will be seedy.
Substitutions
Courgette, Portobello mushroom
Storage
Cool and dry rather than properly cold — below about 10°C the skin pits. A cool larder beats the fridge.
Shelf life
About 5 days
