## Fractional Eggs

I search for new recipes at **allrecipes.com** all the time. This morning, a search yielded a delicious recipe for pumpkin pancakes, which sounded like the perfect breakfast for a crisp fall morning.

One of the things I love about allrecipes is the ability to customize the number of servings. The default number of servings for the pumpkin pancake recipe was six, but I could adjust it to four, a more appropriate number for our two-adult, two-child family:

So I did. And as you’d expect, each item in the ingredient list was reduced to ⅔ its previous amount. Sort of. Two cups of flour was reduced to 1⅓ cups. One cup of pumpkin puree was reduced to ⅔ cup. But 2 teaspoons of baking powder was reduced to 1¼ teaspoons, and 1 teaspoon of cinnamon was reduced to ¾ teaspoon.

The reduction in the number of servings was 33⅓%, yet the range of reductions in the ingredients varied from 25% for salt (from 1 teaspoon to ¾ teaspoon) to 50% for ground ginger (from ½ teaspoon to ¼ teaspoon).

But I get it. It’s not typical for most kitchens to contain a spoon that measures ⅙ teaspoon. So there’s clearly some part of the algorithm that completes the conversion but then finds a “nice” fraction that’s in the right neighborhood. Fair enough.

But what the hell’s going on here?

Is it really better to display ⅝ egg instead of ⅔ egg? Couldn’t the algorithm recognize that fractional eggs just aren’t all that common and leave it as a whole number?

My guess is that the programmer is one of the folks to which this statement alludes:

5 out of 4 people aren’t very good with fractions.

That joke represents one-fifth of my favorite fraction jokes. Here are the other four:

Why won’t fractions marry decimals?

They don’t want to convert.I’m right 4/5 of the time. Who cares about the other 10%?

There’s a fine line between a numerator and a denominator.

Sex is like fractions. It’s improper for the larger one to be on top.

If you find a store that sells ⅝ egg, please let us know about it in the comments.

1.xander | October 19, 2015 at 10:03 amI’ve not encountered a store that sells fractional eggs, but the eggs that we get from the farmer’s market tend to range in size from 1.5 oz to 3 oz (a typical large egg is about 2 oz). Because of this variability, I’ve come to mentally translate “1 egg” to “2 oz of egg.” Maybe you could just get smaller eggs?

Also, does this count as a fraction joke: (because you can cancel the

Acidity of other ingredients can also play a factor. Alcohol and spices also are not usually a linear scale when doubling/halving a recipe.

3.venneblock | October 29, 2015 at 9:24 amYes, it counts as a fraction joke, though I’ve coined the term

malefractionto describe such atrocities.And just FYI, Xander, you can use LaTeX in the comments but you need to put the word “latex” after the first dollar sign. So to make , you need to type “$latex \frac{1}{2}$.” I’ve edited your reply above so the math shows correctly.

Good to hear from you again!
