I have a recipe for key lime pie, which calls for a traditional 9 inch sized pie plate, and I want to use store bought mini graham cracker crusts. It looks like those are sold in sets of 6 - can I prepare the same amount of filling of the normal pie for the 6 mini crusts? I wasn't sure because the regular pie makes 8 servings, so wasn't sure if I should be reducing the filling to 6 servings instead.
