Someone removed the labels from my cake flour and bread flour which are stored in identical containers. Does anyone know a good what to determine which is which?
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
Can you feel a physical difference in your hands? The cake flour should feel lighter than the bread flour.
Perhaps "lighter" isn't the only descriptor for cake flour. It should also feel "softer."
Anyhow, good luck.
If you can't figure it out, just buy more of each. It's not like flour is priced like Italian truffles. Flour is cheap.
You can combine the two unknown flours and use as "all-purpose."
Taste both. I think you will see that the cake flour tastes more "acidic.". Also, it may be whiter.
