How does cake flour smell compared to flour?

Cake flour has a very subtle, almost sweet smell, compared to all-purpose flour. This is because cake flour is milled from softer wheat varieties and has a lower protein content, resulting in a finer texture and a slightly different aroma.

Here's a breakdown:

* All-purpose flour: Has a slightly earthy, slightly starchy smell.

* Cake flour: Has a very subtle, almost sweet, slightly nutty smell.

However, the difference in smell is very subtle and may not be noticeable to everyone.
