Main Ingredients
  • 2 large Sweet Potatoes peeled and cubed
  • 1/4 cup Unsalted Butter
  • 1/4 cup All-Purpose Flour
  • 2 cups Whole Milk warmed
  • 1/2 teaspoon Salt
  • 1/4 teaspoon Ground Nutmeg
  • 1/4 teaspoon Ground Cinnamon
  • 4 Large Eggs separated
  • 1/4 cup Granulated Sugar

Equipment

  • Saucepan
  • Mixing Bowls (2)
  • Whisk
  • 8-inch soufflé dish
  • Potato peeler

Method
 

Instructions
  1. Boil or steam cubed sweet potatoes until tender (15-20 minutes). Drain well and mash thoroughly. Let cool.
  2. Melt butter in a saucepan. Whisk in flour and cook for 1-2 minutes, stirring constantly, until a smooth paste forms (roux).
  3. Gradually whisk in warm milk until smooth and thickened. Simmer for 2-3 minutes, stirring occasionally.
  4. Stir in salt, nutmeg, and cinnamon. Add mashed sweet potatoes and combine well.
  5. Whisk egg yolks. Temper with 1/4 of the warm sweet potato mixture. Pour tempered yolks into the remaining mixture and stir.
  6. Beat egg whites with a pinch of salt until stiff peaks form. Gently fold into the sweet potato mixture in three additions.
  7. Preheat oven to 375°F (190°C). Pour mixture into a greased 8-inch soufflé dish. Sprinkle with sugar.
  8. Bake for 35-40 minutes, or until puffed and golden brown. Do not open the oven door during baking. Serve immediately.

Notes

For a richer flavor, use brown sugar instead of granulated sugar. You can also add a pinch of ground ginger or allspice for extra warmth. Ensure your eggs are at room temperature for best results when whipping the egg whites.
