Mathematicians and dessert lovers alike celebrated March 14 on Monday, a day also known as "Pi Day."

Pi is the term for the ratio of a circle's circumference to its diameter, and is equal to about 3.14.

But because pi is "irrational and transcendental," the number fans behind explain, the digits beyond the decimal continue infinitely without any repetition or pattern. This makes pi a mathematical phenomenon.

For those uninterested in calculations, however, March 14 – or 3/14 – has also become a convenient excuse to indulge in a different type of pie.

Chef Christian Pritchard appeared on CTV’s Canada AM on Monday, with his suggestions for savoury pies to make this March 14.
