Gnu the recipe Maeve linked to looks easy and delicious - if you haven't ever eaten Key Lime pie you should try making this. Key Lime pie is sooooo good - one of my favorites along with pumpkin, cherry, sweet potato, blackberry, apple, chocolate silk, pecan....the only kind of pie I'm not too fond of is lemon meringue.
Now there's a a great aroma - any kind of fruit pie or cobbler baking in the oven on a chilly day.
