Holy Donut The Holy Donut is one of Maine's all-time favorite donut shops. People come out in droves to enjoy their unique potato-based donuts. They announced this week that they'll be bringing back their beloved Margarita donut this Saturday. This green creation is described as having a sweetly tart lime glaze, sugar, and sea salt. And it's available in vegan and gluten-free. Lone Pine Lone Pine Brewing Company is a favorite Maine brewery. They've teamed up with Holy Donut several times before and their latest creation? Just in time for Cinco de Mayo, Holy Donut Margarita Hard Seltzer. Just like the donut, the seltzer will be released on Saturday as well. Want to try both? Lone Pine will be offering free Margarita donuts to celebrate the release.
