Notes
Apples: You can use any variety. Pictured are Granny Smith apples which provide a lovely tartness to complement the sweetness of the potato.Herbs: Not keen on rosemary and thyme? Why not try tossing in curry powder, coriander, or sumac. Looking for a sweeter profile? Try using coconut oil and tossing in cinnamon, cardamon, and/or allspice. Don't Overcrowd: If you overcrowd the pan the sweet potatoes will steam and will become soft and mushy. Two roasting pans are recommended.
