SJgoofy emailed me to ask about how to measure the ground oatmeal in my Chocolate Chip Oatmeal Cookies:
“I just have a question about the ground oatmeal. Do you measure it before or after it is ground?”
Hi there, SJgoofy! You should grind then measure. If you have extra ground oatmeal, you can freeze it in a Zip Loc bag and save it for another batch of cookies. (Hooray!) But, to prevent grinding more oatmeal--or any other "grindable"--than I need, I tend to process the equivalent of only a few handfuls at a time. I then measure what I have and grind more if I need it.
