Ig Nobel Prizes, Koji Alchemy. Nov 27, 2020, Part 2

Laugh Along At Home With The Ig Nobel Awards

We know traditions are different this year. Maybe you’re having a small family dinner instead of a huge gathering. Maybe you’re just hopping on a video call instead of going over the river and through the woods. At Science Friday, our holiday tradition of broadcasting highlights from the annual Ig Nobel Awards ceremony is different this year too. Rather than being recorded live in front of a cheering crowd at Harvard’s Sanders Theater, the ceremony was virtual this year.

But one thing remains the same—awards went to a bunch of genuine scientists for research that first makes you laugh, then makes you think. This year marks the ceremony’s 30th anniversary.

Marc Abrahams, editor of the science humor magazine Annals of Improbable Research and master of ceremonies for the awards, joins Ira to talk about Ig Nobel history, and to share highlights from this year’s winners.

Koji: The Mold You Want In Your Kitchen

When chef Jeremy Umansky grows a batch of Aspergillus oryzae, a cultured mold also known as koji, in a tray of rice, he says he’s “bewitched” by its fluffy white texture and tantalizing floral smells. When professional mechanical engineer and koji hobbyist Rich Shih thinks about the versatility of koji, from traditional Japanese sake to cured meats, he says, “It blows my mind.”

Koji-inoculated starches are crucial in centuries-old Asian foods like soy sauce and miso—and, now, inspiring new and creative twists from modern culinary minds.

And Shih and Umansky, the two food fanatics, have written a new book describing the near-magical workings of the fungus, which, like other molds, uses enzymes to break starches, fats, and proteins down into food for itself. It just so happens that, in the process, it’s making our food tastier.

You can grow koji on grains, vegetables, and other starchy foods, and make sauces, pastes, alcohols, and vinegars. Even cure meats. Umansky and Shih say the possibilities are endless—and they have the koji pastrami and umami popcorn to prove it.

Plus, Urmansky and Shih share some of their favorite koji-inspired holiday dishes and leftover recipes—from turkey amino spreads to cranberry sauce amazake to soy sauce-infused whipped cream. Read more on Science Friday!
