A jug marked with graduated volume scales on its side, used for measuring liquids in cooking. Typically made of glass or transparent plastic with a spout for pouring, the measuring jug lets cooks read quantities of milk, water, oil, or stock at a glance, often in both metric and imperial units. Larger jugs handle up to one or two litres for soups and batters, while smaller ones suit dressings and sauces. Accuracy depends on reading the scale at eye level with the jug on a flat surface. A staple of every kitchen, the measuring jug bridges the gap between rough estimation and precise formulation.
