Which dough testing method would you use to assess gluten development?

• A. Microbial test
• B. Smell test
• C. Windowpane test
• D. pH test

Answer: (C)

Gluten development is about forming a strong, elastic network in the dough through hydration and kneading. The windowpane test directly checks that network: you take a small piece of dough and stretch it gently. If the gluten has developed well, it will stretch into a thin, nearly translucent sheet without tearing, like a windowpane. That thin film shows the dough has enough strength and extensibility to trap air during baking.

If the dough tears easily or won’t stretch, the gluten network isn’t fully developed yet, so you’d need more mixing or resting time to continue developing it.

Other methods don’t reflect gluten structure. A microbial test looks at fermentation activity, not the gluten network. A smell test is subjective and not a reliable measure of gluten development. A pH test measures acidity, not the strength or extensibility of the gluten network.
