In the atlas

Rice feeds more people daily than any other grain. Brown rice is simply rice that kept its bran. Mill it and you have the backbone of gluten-free baking — mild, slightly gritty unless you mill very fine or buy superfine rice flour. Short-grain mills stickier; long-grain mills drier.

Origin. Yangtze basin, China; also independent in India

Flavor. Clean, faint nut, steamed-rice sweetness.

Worth knowing

  • Naturally gluten-free.
  • White rice flour is just brown rice with the bran milled off (or never there).
  • Fresh rice flour tastes sweeter than the bag that's been on a shelf a year.
  • Arsenic can concentrate in rice bran — vary your grains, especially for kids.

Vital wheat gluten booster

Most bags of vital wheat gluten are 75–80% protein. The booster is added on top of the flour, not swapped in.

About 2.7 cups of berries → 3.2 cups of whole-grain flour. Whole-grain milling is essentially 1:1 by weight; sifting is where you lose bran.

How to mill it

Sweet (glutinous) rice is a different starch — great for mochi, not for sandwich bread.

Fine, two passes. Rice is abrasive — expect faster stone wear.

Tempering: No.
