Storage Tips
Airtight container. Lasts 3 months at room temperature, 6 months frozen.
Baking Science
No gluten-forming proteins (but may contain gluten from cross-contamination). Creates moist, tender baked goods.
Recipe Context
For cakes: use weight to avoid dense crumb from over-measuring.
For bread: control hydration by weighing flour and liquids together.
For cookies: 10-20g extra flour can reduce spread noticeably.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Scooping directly from the bag compresses flour and can make bakes dry.
Brand Variance & Measuring Method
Baseline reference: 1 cup oat flour = 95g. In real kitchens, a practical range is usually 84g-106g per cup (12% band).
Why this happens: flours and grains compact differently based on scoop method, humidity, and grind fineness.
