Single-conversion pages for chopped onion
Working with chopped onion
Chopped Onion sits in the fruit & vegetables group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. One medium onion yields about 1 cup chopped. Finely minced onion packs denser.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
