The Lost Kitchen, which may well be the most celebrated restaurant in Maine, is open at last for 2020. Chef Erin French normally opens the restaurant in May but the pandemic has kept the restaurant, located in a former gristmill in Freedom, Maine, closed until now. The good news is that dinner is being served at 10 outdoor tables, with diners chosen through The Lost Kitchen’s famous postcard lottery. French, who authored “The Lost Kitchen: Recipes and a Good Life Found in Freedom, Maine” is a three-time James Beard Award nominee. She is currently the focus of a new show about The Lost Kitchen that will appear next year on the Magnolia Network, a project of Chip and Joanna Gaines, the Texas couple behind the show “Fixer Upper.”
