FAQ

What error margin should I expect on Egg white measurements?
About ±10 % for volume measures, ±1 % for scale measures. Recipes robust to ±10 % work from either; tight bakes need the scale.
Does ingredient substitution change the gram values for Egg white?
The gram-per-cup number is density-specific, so substituting changes it proportionally to the density ratio. Check the new ingredient's density before swapping 1:1.
