These sweet potato burgers are something special. They're made from deliciously spiced patties with the addition of an aioli inspired by nitter kibbeh, also known as Ethiopian butter.

Ginger, garlic, clove, cinnamon, cardamom, coriander, paprika, and cayenne will fill your kitchen with a hypnotic aroma.

- Assemble the burgers by spreading aioli on the bottom buns, adding a burger and topping with the salad. Serve with the top bun.
