Sometime between 1936 and 1938, the Missouri State Society Daughters of the American Revolution published “The Old Tavern; Book of Recipes,” which contained more than 700 recipes from DAR members and the J. Huston Tavern at Arrow Rock State Historic Site. The recipes offered a unique glimpse into our food culture during the early years of the 20th century. On page 36 is a recipe for buttermilk biscuits: “Add to ½ sifter of flour, 1 scant tsp. soda, ¼ tsp salt, 2 level tsp. baking powder. Sift into mixing bowl. Cut in with fork 2 heaping tbsp. lard, 1pt. buttermilk. Turn onto floured board, knead to soft dough, Roll 3/8 inch thick. Bake in greased pan in hot oven. 30 biscuits.” You can try the recipe itself or enjoy the fine food served today at the J. Huston Tavern, the oldest continually operating restaurant west of the Mississippi. For more information, visit
