Measuring Tip
Peanut butter should be stirred before measuring if the oil has separated. An unmixed jar will give inconsistent measurements.
Understanding the Units
What is a Cup?
The US cup (236.588 ml) is slightly smaller than the metric cup used in Australia and some other countries (250 ml). When following recipes from different countries, check which cup standard is being used.
What is a Gram?
Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.
