There are two varieties of this tree. One thrives in the sub tropics, its fruit grows on the trunk. The other prefers more humid climes and the fruit appears in sprays jutting out from the trunk. But both have an acidic plum flavour providing lots of tang.
Davidsons Plum and Macadamia Praline
Whisk together 450gm light brown sugar, half cup evaporated milk, half teaspoon vanilla essence and one tablespoon of unsalted butter in a small saucepan. Boil until it reaches 240F, also called the soft ball stage.
Then add 2 cups dry roasted Macadamias and 2 tablespoons of Davidsons Plum powder. Allow to cool slightly before scooping on to a tray lined with baking paper. Leave to set.
