things people ask

• How much does a cup of quinoa flour weigh?
  About 110 g, spooned into the cup and leveled off — that's the King Arthur figure most US recipes track to. Scooping straight from the bag packs the flour and pushes a cup closer to 125–130 g, which in a small batch of GF brownies or banana bread is enough extra absorption to dry the crumb out noticeably. Spoon and level, or weigh.
• Can I replace all-purpose flour 1:1 with quinoa flour by the cup?
  Not without a fight. Quinoa flour is gluten-free, denser per cup at 110 g versus AP's 120 g, and brings a strong grassy, faintly bitter flavor that overwhelms most recipes when used straight. Standard practice in GF baking is to swap in 25% quinoa flour by weight inside a blend with rice flour, tapioca, and a binder like xanthan gum.
• Why does my quinoa flour taste bitter in baked goods?
  Untoasted quinoa flour carries the same saponin-tinged grassiness that raw quinoa grains have. Spread a cup or two on a sheet pan and dry-toast at 215 F for 1–2 hours, stirring every 30 minutes, until it smells nutty rather than green. Cool, then store airtight. Toasted, it folds into pancakes, brownies, and South American flatbreads without dominating.
