All-Purpose Flour The structure
You're in the flour aisle. All-purpose, bread, cake, self-rising, 'pastry'. Which bag?
The call. Plain all-purpose. Most national brands sit around 10–11.5% protein, which is enough to hold a muffin up. Southern brands run lower and give an even softer crumb.
Looks right
- 'All-purpose' on the front and a protein figure of about 3 g per 30 g serving
- A neutral, faintly sweet smell, like fresh milk and nothing else
- A best-by date at least six months away
Walk away if
- A musty, sour or oily smell: the flour has gone off
- Clumps, or tiny webbing and dark specks, which means pantry moths or weevils
- A torn or damp bag
What if you pick…
Enough protein to support the crumb, little enough to stay tender if the batter is barely mixed.
