What's the equivalent of a "sheet of graham crackers?"
I have an old recipe that asks for "7 sheets of graham crackers (to make a pie crust). Maybe it's just my brand of graham crackers, but it doesn't come in sheets (although I admit to being old enough to remember graham cracker sheets...). Instead, there are three individually wrapped packets of nine 5" x 2.5" crackers in the box. How do I figure out how many of these to use to equate to the quantity I need?
