Local farm stores and orchards that sell cider doughnuts keep their doughnut machines operating all day long on the weekends — sometimes as many as 14 hours at a time — producing thousands of doughnuts to keep up with demand. Eagle Mills Cider Mill and Fun Park in Broadalbin has three machines going at once, as does Lakeside Farms in Ballston Lake. Riverview Orchards’ machine plunges out about a dozen doughnuts per minute, totaling roughly 8,400 on a weekend day.
