Ingredients

Instructions

  1. Step 1: Place 2 peeled and grated medium sweet potatoes (about 500 g) in a clean towel and squeeze out excess moisture.
  2. Step 2: In a large bowl, combine the grated sweet potato with 3/4 cup finely chopped macadamia nuts, 3 chopped green onions, 1/4 cup all-purpose flour, 1 beaten large egg, 1 tsp salt, and 1/2 tsp freshly ground black pepper. Mix until well combined.
  3. Step 3: Heat 3 tbsp olive oil in a large non-stick skillet over medium heat. Shape the mixture into 8 patties about 3 inches wide and place in the pan.
  4. Step 4: Cook the cakes for 4-5 minutes on each side until golden brown and cooked through, turning carefully to keep the shape intact.
  5. Step 5: Meanwhile, in a small bowl, mix 1/2 cup mayonnaise with 1 tsp lemon myrtle powder and 1 tbsp fresh lemon juice until smooth and creamy.
  6. Step 6: Serve the sweet potato cakes hot with a generous dollop of lemon myrtle aioli for dipping.
