Next time you hit the farmers’ markets in Union, Camden, or Rockland, be sure to pick up a pizza along with your salad greens and tomatoes. Uproot Pie Co. (theuprootpieco@gmail.com, 207-370-1568), of Union, travels to these local farmers’ markets with a complete wood-fired pizza oven in tow. For $7 to $9 you can enjoy a fresh nine-inch pie made with ingredients from many of the farmers selling goods and produce at the market. From a fig, gorgonzola, and prosciutto pizza to plain cheese with local sausage or crispy scallions, the pies combine a delicious, chewy crust with the freshest ingredients possible. Founder Jessica Shepard, a native of Cushing, opened the business just this summer (her partner, Andy White, built the oven) and plans to run the mobile pizza operation through October.
