Every day since “Daddy Dave” Leatherby Sr. and his wife, Sally, opened the first Leatherby’s Family Creamery 30 years ago, the shop has been churning out fresh ice cream layered in sweet sauces straight from the candy kettle. Milk, cream, and sugar form the base of Leatherby’s more than 45 flavors, which range from staples such as chocolate and strawberry to more exotic varieties including mocha almond fudge and spumoni. Inspired by family recipes that date back a half-century, these frosty treats come in cones, shakes, malts, and sodas, as well as in heaping sundaes and banana splits, the largest of which tips the scales at 54 ounces. Leatherby’s menu has expanded over time, and includes savory options such as sandwiches, burgers, soups, and salads.
