How to measure granulated sugar
- Ingredient state
- granulated, uncompacted
- Measurement method
- spooned level
Measurement notes
- Granulated sugar pours and settles fairly consistently, so cup measurements are more reliable than flour.
- Spoon sugar into the measuring cup and level off the top with a knife for consistent results.
- Fine or superfine sugar packs slightly denser than standard granulated sugar, so weights can vary by a few grams.
- A kitchen scale removes any guesswork when a recipe needs precise sugar amounts.
