33 Facts Showcasing the Macadamia

There's no doubt that macadamias are the heart and soul of Brookfarm. It starts on the family farm all the way back in the beginning where the Brooks planted 4,500 macadamia trees. Pam Brook, the co-founder of Brookfarm, decided selling macadamias covered in chocolate did not do the nut justice and that's what sparked the idea of our favourite Toasted Macadamia Muesli.
