Roast the Macadamia Nut in a saucepan until it gets brown

In a blender, add the roasted nuts and 2 cups of water and blend on high for 2 minutes (it will look like a brown mash)

 Pour the mash into a nut-milk bag over a bowl, and squeeze as much liquid as possible (if you don't have a nut milk bag, strain through a fine-mesh sieve covered with a few layers of cheesecloth)

In a saucepan combine however much liquid you were able to squeeze out of the mash and add the same amount of sugar. Turn the heat and stir until the sugar is dissolved (bringing to boil is not necessary). Remove from heat and let it cool

Rinse the blender. Add the sweetened liquid, Frangelico, Gum Arabic, Xanthan Gum and the Rose Water and blend on high for 1 minute

Transfer to a clear container or bottle and refrigerate. (good for up to 3 weeks)
