I took advantage of the perfect opportunity the other night to ask this question to Sara Moulton who was giving a talk about the new Gourmet Cookie Book. Now in all fairness to her, she does way more cooking than baking, and she said this, so her answer to me was to call the nice people at King Arthur Flour to get an accurate answer.Then she wants me to email her with the answer.
So I called KA the next morning and here was their answer... 4 ounces. No, I replied, that can't be correct, I said. The woman on the other end of the phone said, well there are 16 ounces to our pound of flour, so 4 into 16 equals 4 so the answer's 4. Well that doesn't make sense.
Well, I measured 4 ounces of flour, fluffed and whisked and lightly scooped into the measuring cup and the photo above shows what 4 ounces of flour in my measuring cup looks like. The flour doesn't even come close to the top..so I'm putting this question out there to anyone who can shed some light on this. I did receive one answer from Anna and she said 4.5 ounces. How many ounces does 1 cup of all purpose flour weigh?
