Ingredient

Apple

The variety matters more here than with almost any other fruit, because cooking apples collapse into sauce and eating apples hold their shape. Choosing wrong is the usual reason a tart comes out watery or a crumble comes out chunky.

Sourcing
Best from a greengrocer or farm shop in autumn, when the range goes well beyond the four varieties supermarkets stock year-round.
Varieties
Bramley, Granny Smith, Braeburn, Pink Lady, Cox, Honeycrisp
Quality cues
Heavy for their size and firm all over. Press near the stem — any give there means it has been in storage a long while.
Substitutions
Pear, Quince
Storage
The fridge drawer, not the fruit bowl: they keep several times longer cold. Keep them away from other produce, as they give off ethylene and ripen everything nearby.
Shelf life
1-2 weeks at room temperature, 1-2 months refrigerated
