The 1940s and 1950s saw the rise of the potato doughnut. At one point, there was a chain of Spudnut shops across the country; the chain no longer exists, but some of the independent shops still do, like this one in Washington state.
A family recipe provided by Jennifer Kiel of Washington, DC, from her mother-in-law’s collection, started in Kent, Ohio.

2 beaten eggs
1 cup sugar
2 Tbsp. salad oil
