Frequently asked questions

Why do cups-to-weight conversions vary?
Different ingredients have different densities. Flour can vary 10–20% depending on how it is scooped.
Should I sift flour before measuring?
Sifted flour is lighter (~110 g/cup). Spooned and leveled is ~125 g. The recipe should specify.
What is packed vs unpacked brown sugar?
Packed brown sugar is pressed into the cup: ~220 g. Loose is ~165 g.
Why weigh instead of measure?
A kitchen scale eliminates ambiguity — professional bakers always use weight measurements.
