Ingredient

Beetroot

Earthy from a compound called geosmin, which some people taste far more strongly than others — that is the real reason beetroot divides opinion. Roasting whole in foil concentrates the sugars; boiling leaches both colour and flavour into the water.

Sourcing
Buy with the leaves still on where you can — they are a good chard substitute and their condition tells you how fresh the root is.
Varieties
Red, Golden, Chioggia, Cylindra
Quality cues
Firm with smooth, unwrinkled skin. Small to medium roots are sweeter; very large ones can be woody at the core.
Substitutions
Carrot, Sweet potato
Storage
Twist the leaves off before storing or they draw moisture from the root. Roots keep well in the fridge drawer.
Shelf life
2-4 weeks refrigerated; leaves 2-3 days
