Questions & answers
Frequently Asked Questions
Does crystal size or packing change the result for Caster Sugar?
Caster Sugar keeps one reference basis here, but crystal size, moisture, and caking can shift how much fits in a spoon or cup. That matters more with sugars and sweeteners than with a purely liquid measure.
