All materials are measured level, i. e., by filling cup or spoon more than full and leveling with a case knife. This applies to liquids which "round up" in spoons. Flour, meal, and fine sugar are measured after sifting. Measuring cups are not always accurate and ordinary tea and tablespoons vary considerably.
Test spoons with each other and with the cup before using.
