    SNAP To It! Why Food Stamps Matter To All of Us—And Why They're Under Threat

    2026-03-10 | 46 mins.
    SNAP—the federal assistance program better known as food stamps—helps put food on the table of nearly one in eight Americans today. But, as new legislation is phased in over the coming months, more than half of those people are expected to lose some or all of their SNAP benefits. This episode, we're getting to the bottom of why SNAP matters—to all of us, not just those who receive it. Why does the U.S. government give people money just for food, rather than cash, as in other countries? Does it make sense to ban SNAP from being used to buy junk food? And why are so many people still hungry, when American farmers produce more food than we can even eat? For decades, the food stamp program has been the main way the U.S. government puts food on the tables of folks who would otherwise struggle to afford it; for all of those decades, it's been attacked, resented, and subject to political horse-trading. Listen in now, as we explore how SNAP has survived for so long—and whether it's worth saving today.

It turns out the sweet, syrup-covered stack of American breakfast fame are far from the only members of the pancake family—and there are some truly controversial cakes in the wider pan family. Speaking of controversy: if you've made instant pancakes from a certain famous mix, you might not realize the racist history behind it. Join us for the shocking story of Aunt Jemima, stay for the great pancake debate, and don't blame us if you end up craving something flattish, fluffy, and floppy for your next meal!

    OXO, Cuisinart, and Julia Child: The Secret (Accessible) History Behind Your Kitchen

    2026-02-10 | 51 mins.
    For many people with disabilities, the kitchen can seem a deeply unfriendly place. From counters that require users to stand and cabinets that are often out of reach, to ovens that can’t be opened in mobility chairs and tools that are hard to grip or difficult to read—cooking can seem like an impossible challenge. But it doesn’t have to be this way. In fact, since the mid-1900s, researchers, designers, and people with disabilities have worked together to reimagine the kitchen in ways that have made it better for all of us. Listen in for this hidden history behind many of your favorite cooking tools, from OXO Good Grips to the Cuisinart food processor, as well as the inspiring stories of how today's blind and disabled cooks have hacked their kitchens to achieve both dinner deliciousness and culinary glory.
