Ingredients

For Sweet Potatoes

  • 4 lb red-skinned sweet potatoes (or yams) (peeled, cut into 1-inch pieces)
  • 5 tbsp Round Pond Italian Varietal Extra Virgin Olive Oil
  • 1 tsp ground cinnamon
  • 1 tsp ground thyme
  • ½ tsp salt
  • ½ tsp pepper
  • ¼ tsp ground nutmeg
  • ¼ tsp ground clove
  • ¼ tsp ground cardamom
  • 1 cup Steen's Southern Cane Syrup

For Fernet Marshmallows

  • 110 g egg whites (with a pinch of cream of tartar)
  • 800 g sugar
  • 180 g water
  • 30 g gelatin
  • 57 g Fernet Branca (Italian Bitters)

Directions

For the Sweet Potatoes

  1. Preheat oven to 375F. Toss sweet potatoes in olive oil, spices, salt, and black pepper. Arrange potatoes in 13 x 9 x 2-inch glass baking dish or casserole dish of your choice and bake until tender. Remove dish from oven and coat roasted potatoes with Steen’s Southern cane syrup. Return to oven and bake until sticky, about 15 additional minutes.

For the Fernet Marshmallows

  1. Bring sugar and water to 245 degrees in a saucepan over medium heat. Bloom gelatin according to directions. Whip egg whites (with a pinch of cream of tartar) to stiff peak in mixer.

  2. Drizzle in hot sugar syrup to egg whites to temper, and then add the rest of the sugar syrup, add Fernet and gelatin. Fold in softly. Spread marshmallow mixture on the top of potatoes and place under broiler to give your marshmallows a s’mores-like look.*
