Estimating for baking...
Ok, if I make my average 30 dozen (or so) Great Cookies, that's about 3 pounds of flour, and a dozen eggs, 6 cups of peanut butter, 3 lbs of butter, 6 cups of brown sugar, 6 cups of sugar, and 6 cups of chocolate chips.
Here's a handy pounds-to-cups table, too.
So, I'll be bringing plenty of bowls and such to Fab J's, too.
