Pi = 3.14159265359…

This Saturday is March 14, 2015… or 3.14.15!  And, on that magical day at 9:26 and 53 seconds (3.14.15 9:26:53), I suspect a lot of math fans like me will be eating pie to celebrate its magical homonym Pi.  Mmmm….

Pie can be tricky for people with food allergies for so many reasons.  They typically contain dairy, sometimes contain eggs, often are topped with nuts.   And, of course, that gluten-filled crust.

If you’re planning to celebrate Pi Day, here are a couple recipes to help you and your little calculators eating safely:

Sweetheart Sorbet Pie:

This cold, delicious, fruity pie is a synch to assemble and a joy to devour.

Egg-free, Dairy-free, Nut-free

Moo-Less Chocolate Pie:

If you’re a chocaholic like my younger son, this recipe is for you.  Alton Brown’s recipe uses silken tofu to achieve its creamy, fudgey consistency.  Be sure to use dairy-free margarine/butter in lieu of the milk-based variety.  Read the reviews to determine if you want to include any of the readers suggestions (like adding cinnamon or using a graham cracker crust).

Dairy-free, Nut-free, Egg-free

Crazy for Crust’s Perfect Graham Cracker Crust:

This blogger really knows her crust as evidenced in the narrative leading up to the recipe.  Again, be sure to substitute dairy-free margarine/butter for the real deal in her recipe.

Egg-Free, Nut-Free, Milk-Free ***but also read ingredient list of graham crackers/crumbs you choose to use***

Gluten-Free Pie Crust:

This ready made dough from Pillsbury can be used in both pies and pastries.

Gluten-free, Dairy-Free, Egg-Free, Nut-Free

Here are some Pi facts to discuss over pie:

  • Pi is the ratio between the circumference (the distance around its edge) of a circle and its diameter (the distance across the center).
  • Pi is an irrational number. Not only can’t you reason with it, but you can’t write it as a fraction either.
  • Pi’s decimals go on forever without any repetition or pattern.
  • BUT! 314159, the first six digits of Pi, appear in order at least six times among the first ten million decimals of Pi.
  • Albert Einstein was born on Pi Day!
  • Pi has been studied by the human race for almost 4,000 years. The Babylonians established the constant circle ratio as 3-1/8 or 3.125.  One of the earliest known records of pi was written by an Egyptian scribe named Ahmes (c. 1650 B.C.) who was only off by less than 1% of the modern approximation of pi (3.141592).
  • In one Star Trek episode, Spock foils an evil computer by challenging it to “compute to last digit the value of pi.”
  • Comedian John Evans once quipped: “What do you get if you divide the circumference of a jack-o’-lantern by its diameter? Pumpkin π.
