Rye flour references need a clear product description. BatchLadle keeps King Arthur’s medium rye record separate from the Women’s Weekly Food rye-flour record, whose grind is not specified.
Read the grind description
The medium rye reference does not cover every rye blend, pumpernickel product, or grind. Keep the name from the recipe or package in your note when deciding whether it matches.
The Women’s Weekly Food reference defines a level 250 mL cup but does not resolve the rye grind. A defined cup volume improves the unit basis without filling that product-information gap.
Choose one relationship deliberately
Use the source selector to keep the published relationships separate. Do not average them or change source merely to make a desired output available.
For a recipe already written by weight, direct scaling avoids the need to decide how its flour would fill a source cup. Keep the original mass as the calculation basis.
Keep rye visible in a flour blend
When rye is one of several flour rows, include its mass in total flour but preserve its individual quantity. That makes the original blend readable after scaling.
If the recipe names a premixed product, do not treat the entire product as pure rye without knowing its composition. A blend description can stay as a manual ingredient with its own original amount.
