During a recent visit to the Birchwood Cafe in Minneapolis, chef and author Beth Dooley showed PBS NewsHour Weekend how to cook Kernza pancakes.
The cafe, a local institution known for its commitment to local and sustainable ingredients, was one of the first restaurants to start cooking with Kernza, an experimental grain similar to wheat. Twin Cities chef and author Beth Dooley helped Birchwood develop its Kernza recipes and co-authored the “Birchwood Cafe Cookbook.”
Future of Food: How a new grain could help combat climate change
So, what is Kernza? As we’ve been reporting in our “Future of Food” series, most of the plants that we eat are annuals, which die in the fall and are then replanted the next year. And that process has a host of negative impacts on the environment. Tilling the soil to prepare it for seeding can damage the land and release carbon dioxide into the atmosphere. And after plants die in the fall, cropland often has nothing growing on it for months, which can lead to erosion and water contamination.

Back in the 1980’s, scientists at The Land Institute in Kansas started to develop a perennial grain, genetically similar to wheat, that is now known as “Kernza.” It’s a tall version of intermediate wheatgrass that can live for more than a decade.
Kernza has extremely long roots, which stay in the ground for years, helping trap carbon dioxide and protecting soil health and water quality. Kernza can also provide wildlife habitat. And farmers can get a lot of bang for their buck because it’s a “dual use” crop: cattle can forage it in the spring before the grain is harvested later in the fall.

Proponents now want to make Kernza a mainstream, commercially viable grain. But there are a lot of hurdles. Compared to annual wheat, Kernza’s seeds are tiny and the plant’s overall yields are about 75 percent less. And those yields tend to drop off after about three years.
Scientists at the University of Minnesota, which has one of the largest Kernza research programs, are hard at work selectively breeding the plant to solve some of the issues. And the University’s “Forever Green Initiative” is getting food producers big (like General Mills) and small (like Birchwood), interested — ensuring that when, or if, Kernza ever hits the big-time, there will be a market for farmers to sell to.
“It’s healthy for the soil, it’s healthy for communities, it’s healthy for people,” said Tracy Singleton, Birchwood’s founder. “There’s so many things that I was just really drawn to. So, I was very excited to get to be a part of it.”
About five years ago, a University of Minnesota researcher dropped off a 50-pound bag of Kernza and Birchwood’s chefs and bakers started experimenting. It’s high in protein and antioxidants. But its gluten content is lower than traditional wheat, so bread baked with Kernza flour, for instance, doesn’t rise quite as high. Today Birchwood uses Kernza in everything from crackers to tortillas, desserts (in a puffed form) and in pancakes.
