About mayonnaise measurements
Mayonnaise is an oil-in-water emulsion, and the reference density here is about 0.97 g/ml, or roughly 230 g per cup. Light mayo is thinned with water and whipped air, so it spoons lighter than full-fat; pressing it firmly into the measure squeezes out pockets and steadies the weight.
