Just seems bizarre that we are baking blueberry pies in one slice at a time. (While making apple and pumpkin pies the size of bagels)
Howsaboot, we bake them as 1x2 sized items (fits four in the oven) and slice them into 2-3 slices (or just eat them whole!.. you gratuitous gluttonous gourmand pig) - Increase the recipe requirements if neccessary, but I think this would be neat.
