Powdered sugar, confectioners’ sugar, and icing sugar can appear in recipe wording, but the selected reference still needs a defined scope. BatchLadle preserves the description used by each publisher.
Use the unsifted record when it matches
The King Arthur reference is for unsifted confectioners’ sugar. It does not establish the same volume relationship for an already sifted measure.
Keep the sequence in the recipe: measuring and then sifting is a different instruction from measuring sugar that has already been sifted. Leave the original wording in the note if its meaning is uncertain.
Read the icing-sugar limitation
Women’s Weekly Food gives an icing-sugar relationship using its 250 mL cup. The consulted entry does not state whether the product is pure icing sugar or a mixture, or whether it was sifted.
That source can be selected with its limitations visible. A defined cup volume does not resolve those missing product and preparation details.
Prefer the recipe’s existing weight
When your recipe provides grams, scale the stated mass directly and keep sifting as a method note. A cup estimate is unnecessary for changing the batch size.
Keep powdered sugar separate from granulated sugar in shopping totals. If you use a particular icing mixture, preserve its name rather than silently replacing it with a generic sugar entry.
