Is it Pi Day or Pie Day? Let’s celebrate both — the mathematical infinite and the scrumptious dessert. Pi Day is observed on March 14 around the world, chosen because the numerical date is the first three digits of pi (3.14).

Pi is the symbol used to represent a constant — the ratio of the circumference of a circle to its diameter — and, appropriately, we’re celebrating our constant and infinite love for pies.

What better way to celebrate than with some all-time favorites from our “Electric Kitchen” archives.

>> Tip: To cut a perfect slice of pie, dip your knife in hot water quickly, wiping it dry before cutting.
