  • 3/4 cup pureed sweet potato
  • 4 Tablespoons cold buttermilk
  • 1 1/4 cups all-purpose flour
  • 1/2 teaspoon fine sea salt
  • 1 Tablespoon baking powder
  • 1/2 teaspoon baking soda
  • 1 Tablespoon cane sugar
  • 2 Tablespoons cornstarch
  • 1/4 cup unsalted butter chilled
  • 1/2 cup cooked red split lentils well drained and cold

For the glaze (optional)

  • 1 Tablespoon salted butter melted
  • 1 Tablespoon pure maple syrup


  • Preheat the oven to 425F. Lightly oil a rimmed baking sheet.
  • In a small bowl, whisk together the sweet potato puree and the buttermilk. Place in the refrigerator to chill while you prepare the remaining ingredients.
  • In a medium bowl, sift together the flour, salt, baking powder, baking soda, sugar and cornstarch. Whisk well to combine.
  • Using the large side of a cheese grater, grate the cold butter into the dry ingredients. Use your hands to partially rub the butter into the flour. It's okay if there are still small, pea-sized pieces of butter.
  • Add the lentils to the bowl and toss with your hands to coat them in the flour.
  • Scrape the sweet potato/buttermilk mixture into the flour. Using a spatula, gently fold the ingredients until they just come together.
  • Generously flour your work surface and empty the bowl onto it. Gather up the dough into a ball, incorporating all the odd bits. Knead it 2-3 times until it comes together.
  • Pat the dough gently down to 1-inch thick. Cut into rounds using a floured 1 1/2 inch biscuit cutter.
  • Gently transfer the biscuits to the baking sheet. Press the scraps together and keep cutting biscuits until all the dough is used up. You should have 16 biscuits.
  • Whisk the melted butter and maple syrup together and brush onto the tops of the biscuits.
  • Place on the center rack in the oven and bake for 10-12 minutes (ovens will vary) or until light golden and the tops spring back when touched.
  • Partially cool on a wire rack; enjoy while still warm with additional butter and maple syrup.


Make sure the sweet potato purée is not overly watery. If necessary, set in a fine-mesh sieve for 30 minutes or so to drain out a little of the liquid before using.
