Liquids

Substances that self-level in the cup: milk, cream, yogurt, purees, semi-liquid pastes. Measurement noise is small because self-levelling removes the fill-method variable.

This is where the site’s fluid-ounce rejection pattern sits. King Arthur’s chart publishes 227 g per cup for many hydrated dairy products, which is the weight of eight avoirdupois ounces rather than a bench measurement of the substance. Where a source figure fails physics — a density lighter than water for something that must be denser than water — it is recorded with the rejection reason and USDA’s measurement is published instead. Held to 5% tolerance for sources that survive the physics check.

65 ingredients in this category. 57 with a single published figure, 8 published as ranges because sources disagree.
