About Water & Milk

Water defines the kitchen's volume-weight bridge: 1 US cup = 237 ml = 237 g, and the milliliter-gram equality holds for everything water-like. Milk runs 244 g (the fat and milk solids add mass). The metric cup (250 ml) is the classic trap in translated recipes — 5% more volume, harmless in stews, meaningful in brioche.
