Not All Ingredients Weigh The Same

Remember when using your scales, generally no two ingredients weight the same. For example a cup of flour (150g/5½oz) doesn't weight the same as a cup of cocoa powder (105g/3¾oz), nor the same as a cup of caster sugar (220g/7¾oz). So, if a recipe doesn't specify the weight of an ingredient make sure you don't ever presume its weight by comparing it to another.
