Measurement Tip
Measure water in a liquid measuring cup (the kind with a spout) placed on a flat surface. Read the measurement at eye level, looking at the bottom of the meniscus (the curved surface of the liquid). For sticky liquids like honey, lightly coat the measuring cup with oil first to help it slide out easily.
