How to measure wet ingredients
Start with a liquid measuring cup.
Liquid measuring cups are the most accurate way to measure thin liquids, like water, milk, juice, and oils. They are made of transparent glass or plastic, and have markings on the sides to indicate volume in both metric and english units.
You can find one at a grocery store, big-box store, kitchen-supply store, or even a dollar store. Place the cup on a flat surface.
