Ingredient

Asparagus

A short spring season and a fast decline after cutting — asparagus starts converting its sugars the moment it leaves the ground, which is why the difference between a farm-shop bundle and an air-freighted one is so stark.

Sourcing
Buy in season and locally where you can. Thickness is not a quality grade — thick spears are not woodier, they simply want peeling at the base.
Varieties
Green, White, Purple, Sprue (thin)
Quality cues
Tight, closed tips and squeaky, firm stalks. Splayed or damp tips and dry, split cut-ends mean it has been sitting.
Substitutions
Tenderstem broccoli, Green beans
Storage
Trim the ends and stand the bundle upright in a centimetre of water in the fridge, like cut flowers.
Shelf life
3-4 days refrigerated, best the day you buy it
