This is a family favorite, and a nice change from the usual lemon meringue pie. It's well worth the extra work. I've used pre-made pie shells, and they work just fine. And I have never yet been able to fit all the filling into one pie. I always end up with two, even though the original recipe says it makes one. This is a good 'make-the-day-ahead' pie. "Cook time" here is actually "chill time." This is from my favorite cookbook, The Creative Cooking Course edited by Charlotte Turgeon.
