Instructions

  1. Step 1: Preheat oven to 350°F (175°C). In a large bowl, toss 4 cups mixed berries with 1/2 cup granulated sugar, 2 tbsp lemon juice, and 1 tbsp ground wattleseed until fruit is evenly coated.

  4. Step 4: Stir in 1/2 cup chopped macadamia nuts for crunch.
  5. Step 5: Sprinkle the crumble topping evenly over the berry mixture.
  6. Step 6: Bake uncovered for 40-45 minutes until the topping is golden brown and the fruit filling is bubbling around the edges.
