What better way to celebrate everybody’s favorite mathematical constant and consequentially also March 14th than a firm full of engineers bringing all the pie to the table (and the gauntlet has been thrown down to lovers of "e" everywhere). I dusted off my baking skills to join in the festivities and with a little inspiration arrived at making a Bumbleberry pie. What is a bumbleberry exactly? Well I was about to find out as I embarked on the delicious and berry filled adventure to pay tribute to Pi.
Bumbleberry Pie
Servings: 2 Pies (What? You were seriously gonna celebrate Pi Day with just one pie?)
Time: 90 Minutes

Pie Crust
5 1/2 cups all-purpose flour
1/4 teaspoon salt
2 cups shortening
3/4 cup cold water
1 egg
1 tablespoon vinegar
Pie Filling
2 cups chopped fresh rhubarb
2 cups sliced fresh strawberries
2 cups fresh blueberries
2 cups fresh raspberries
2 tablespoons lemon juice
2 cups white sugar
2/3 cup all-purpose flour
2 tablespoons tapioca
1 egg yolk beaten with 2 tablespoons water to brush the top
Preparing the Crust
- Fold the shortening into the flour and salt until crumbly.
- Whisk together the water, egg, and vinegar in a separate bowl.
- Mix the wet mixture into the dry until it forms a ball.
- Divide the dough into four balls and refrigerate for at least 4 hours.

(The rolling pin was at the old place still, so this was done by hand. Most impressive.) |
Preparing the Filling
- Preheat the oven to 350 F.
- In a large bowl, mix together the apples, rhubarb, strawberries, blueberries, raspberries, and lemon juice.
- In a separate bowl, mix together the sugar, flour and tapioca.
- Slowly mix in the blended dry ingredients with the fruit mixture.
- Divide the mixture into two pie plates each lined with one of the balls of dough.
- Roll out the remaining two balls of dough to form the tops.
- Brush on some of the egg wash.
- Bake in the preheated oven for about 60 minutes until the top is a golden brown.
- (Let cool quaintly on a windowsill.)
Though I was nervous that my pie-making skills had waned, a quick taste quickly restored my confidence. The 2pm (no, no, not 3:14) pie festivities at work brought out quite the variety and everyone seemed to enjoy the oddly-named Bumbleberry Pie.

(When asked for a comment on how it actually tasted, Kevin simply responded "like an explosion of berries," so I decided to help him out. While this is a truthstory, it does not do justice to said explosion. There are a wild 5 different kinds of fruit in the pie (six if you count the lemon juice) causing it to pack a powerful punch. Instead of just getting lost in a sea of compoted pie filling, each component hits you at a different time leading to a truly killer pie experience that's kind of like a real life realization of the everlasting gobstopper from Willy Wonka. The end result is a nicely sweet and quite tart pie that truly does justice to the master of the circle- pi)
How to quiet any group of scientists.
