Combine dry spices in a small dish or cup, and set aside.
Peel and mince or grate the fresh ginger root. You should have about 1-2 teaspoons worth of finely grated or minced ginger.
If you're using fresh turmeric root, peel it and set aside with ginger - it will easily blend so there is no need to chop or grate it.
Place the milks, Brain Octane oil, and honey into a blender and blend til evenly mixed. Add the spices and root(s), and blend again. You can also use a quart sized container with an immersion blender for this task.
Pour the milk mixture into a pot and heat gently on the stove, til steam is rising. Do not boil.
Remove from heat once hot but not boiling, and strain the mixture back into your blender. Let it cool for a minute or two, then add the protein powder and blend briefly til smooth. Serve warm.
If you like, you can skip the strainer and drink the milk with ginger in it, if minced or grated finely enough.
