The only common grain whose proteins form gluten in quantity, which is the entire reason bread rises, pasta holds its shape and noodles can be pulled by hand.
Where it comes from
Wheat was domesticated in the Fertile Crescent — the arc running from the Levant up through south-eastern Turkey and down into Iraq and western Iran — from wild grasses, beginning with einkorn and emmer. Modern bread wheat, Triticum aestivum, is a later hybrid with a third wild grass, and it is that accident that gave it the gluten strength nothing else in the grain family has.
It now covers more of the world’s farmland than any other food crop, which is less about flavour than about climate: wheat grows in temperate zones where rice will not, and stores dry for years.
Varieties
- Bread wheat — Hard, high in protein, the flour for anything that has to trap gas and hold it. Most flour sold as strong or bread flour.
- Durum — The hardest wheat of all, ground to semolina rather than fine flour. Pasta, couscous and North African breads.
- Soft wheat — Low protein, weak gluten. Cakes, biscuits and pastry, where structure is the enemy of tenderness.
- Spelt, emmer, einkorn — Older species with husks that cling to the grain. Nuttier, weaker gluten, and back in use for flavour rather than yield.
- Freekeh and bulgur — Not varieties but treatments — freekeh is young wheat roasted green, bulgur is mature wheat parboiled and cracked.
In the kitchen
Gluten is not in the flour; it is made when flour meets water and is worked. That is why the same bag produces a tight crumb or an open one depending only on how it was handled and how long it was left.
Protein content is the number that matters when choosing a flour, and it is usually on the packet. Roughly: under 10% for cakes, 10–12% for general use, above 12% for bread and pizza.
Choosing and keeping
Wholemeal flour contains the germ, which carries oil, and oil goes rancid. It keeps months rather than years, and better in the freezer than the cupboard.
White flour keeps far longer but is not immortal — a stale, faintly cardboard smell means it has been open too long.
