Let’s cook with it → Invent something with it

What it is for

They build structure. Starch granules swell in hot water, burst, and weave a net that traps the liquid — most of what you call body comes from here. Wheat does one extra job on top: gluten.

Where it catches you out

Starch does nothing before 62 °C, and acid cuts the chains during a long boil. Think about your thickener after the heat and before the acid.

The knack

Sifting does not remove lumps, it aerates: the same weight takes more space. Weigh it, never scoop it.

Storage and health

How to keep it, and who it suits.

Keeping it

Airtight in a cool dry cupboard for 6-8 months; wholemeal is higher in fat, so refrigerate it and use within 3 months.

Contains gluten

Wheat flour is a direct source of gluten: the gliadin and glutenin proteins are in the wheat itself.

Allergen: GLUTEN

What it works with

Pairings, and the reason for each

"They go well together" is not an explanation. Every pairing below has a chemical or structural mechanism under it.

Water

Hydration is not a step before the reaction, it is the reaction: dry flour contains no gluten. Glutenin and gliadin only build the viscoelastic network once water arrives.

Salt

Sodium and chloride screen the negative charges on glutenin chains; with less repulsion they pack closer and the dough strengthens. Salt also inhibits the flour proteases that would degrade gluten.

Butter

Fat coats the hydrated protein strands and physically interrupts gluten continuity. That is why the same flour gives bread with water and crumbly pastry with fat.

Also works with

What it fights with

Vinegar

A serious dose of acid depolymerises gluten and over-slackens the dough.

Baking soda

Soda without acid raises the pH, leaves a soapy taste and yellows the wheat flavonoids.

What goes on top
  • Egg wash, sesame, nigella, butter brushed on hot pide, honey or molasses
Key compounds
Glutenin / gliadin
Set irreversibly at 70–80 °C, locking the crumb structure.
Amiloz / amilopektin
Gelatinise at 55–70 °C then retrograde on cooling: that is staling.
Nutritionally

Wheat protein is limiting in lysine and incomplete on its own; legumes complete it. The old rule that they must be eaten in the same meal was withdrawn in 1988 — across the day is enough.

Terms on this page
Gliadin
Wheat’s other main protein. With glutenin it forms gluten, and it is the one that causes trouble in coeliac disease.
Glutenin
One of the two main wheat proteins. With water it builds the web that gives dough its elasticity.
