Key Lime Pi

Step 6: The Reveal

Cool on a rack for 10 minutes, then dust with graham cracker crumbs to highlight the ridges left behind by the template. Try not to use much more than you need; if there are too many crumbs, they won't all stick to the cooking spray on the top of the template, making it hard to remove the template without spilling. You can also skip the crumbs entirely if you prefer; the template will actually leave subtle but still visible ridges in the pie filling.

Now comes the hard part. Using the tip of a knife, pull up the edge of the template. It should release from the pie without much effort. Continue pulling up the template, working evenly from both sides towards the center. The excess graham cracker crumbs will probably stick to the cooking spray on the top of the template, as long as there aren't too many, but do try to be careful not to spill them where they shouldn't be.

Lastly, we'll add a decimal point to our π. Dip the end of a drinking straw into a dish of graham cracker crumbs; you want to pick up enough crumbs to make a dot, but not so many that the dot will overflow into the rings. Keep the crumbs from falling out by covering the bottom end of the straw with a finger, then position the straw over the pie between the 3-segment ring and the first 1-segment ring. Remove your finger, letting the crumbs out.

Refrigerate the pie for a few hours or overnight, then serve and enjoy!
