What would happen if you ran out of bread flour but still wanted to make bread? Or the store had an awesome sale on cake flour which you were tempted to use instead? Flour is basically just flour, after all, no? There’s not much difference between Pastry and All Purpose, besides a bit more protein, right?
As an experiment, the class did a test this week to see what each of four types of flour could make, using the same recipe for each and changing only the type of flour used. The recipe was put together by team of Chelsea, Connor and Lauren.
We tested simple panned bread loaves made from:
Organic Bread flour
All Purpose flour
Each batch were made with the exact same ingredients except for the flour, in the same quantities and mixed in four identical 10-quart mixers. Each mix made four identically sized loaves and baked for the same amount of time. Although not under strict laboratory controlled conditions, these were, in effect, identical breads.
Here’s a question that seems to pop up on a fairly regular basis in the bread forums. Someone sees a recipe that requires 3.5 cups of flour, or one that looks for 368g of flour. Either way, they’re used to the other method of measuring and they run into problems making the conversion from one to the other.
Why is it confusing? Because one is a volume measure and the other is a weight measure. As we all know a cup is not always a cup: a cup of rocks and a cup of feathers will not weigh the same. Simply stated, volume and weight are not a consistent and easily interchangeable form of measure. Add in the confusion of liquid vs dry ounces and cups and you have a mess.
But there’s probably a set “standard” weight for flour, right? I mean, measuring flour is something people do ALL the time and have done for eons so someone, somewhere probably has The Definitive Weight for a “cup of flour”.
