Math has never been my favorite subject. If there was one black mark on my quarterly report card, it would be filed under algebra, or calculus. Quite frankly, it’s a small miracle that anyone let me graduate with such a flimsy understanding of numbers in general. One limited concept that I can comfortably wrap my mind, and my lips around, is pi.
Okay, you got me. Not actual pi, but pie. Flaky pastry and comforting fillings both sweet and savory always make perfect logical sense. Pi Day, March 14th (3.14) is the only day of the year I’m happy to bridge the gap between baking and calculating.
This year, I’d like to present to you an appropriately educated provision. Inspired by daigaku imo, imagine a chunky sweet potato pie with a touch of Asian flare. Directly translated, daigaku imo means “university potatoes.” Though still murky in origin, the name can be traced back to two plausible explanations.
Tokyo University, sometime in the early 1900’s, saw the rise of this cultural sensation. Some say a snack shop began offering lightly fried sweet potatoes drenched in sugar syrup and tossed with sesame seeds, while others are adamant that it was a student selling these sweet and savory delights to raise funds for tuition. Either way, we have Japan to thank for yet another viral food hit.
Rather than pulling out a vat of bubbling oil, my adaptation uses only a touch of toasted sesame oil to roast the tubers to fork-tender perfection. Creamy yet still toothsome, the pale white flesh takes on greater dimension with the umami notes of soy sauce rather than plain salt, plus the acidic edge of vinegar for balance. These subtle, delicate nuances will keep tasters guessing, but this is a culinary equation that’s easy to solve.
