Yeast-raised donut with mashed Maine potato in the dough, producing a moist, dense, chewy bite distinct from American cake donuts. Leigh Kellis built The Holy Donut in 2012 around Maine Russet, Yukon and sweet potatoes.
The Holy Donut on Park Avenue opened in 2012 from Leigh Kellis, who reworked her grandmother's potato-dough recipe into a commercial bakery program built entirely on Maine potatoes (Russet, Yukon Gold, sweet). Potato in donut dough is not new (American potato donuts date to the 1800s), but Kellis built a single-product Portland business around it. Three Portland locations plus Scarborough now run the same daily-changing flavour board.
