One of the best parts about this recipe is that it can be fine-tuned to your needs. Need more? Duplicate the recipe. Need less? Cut the recipe in half. Alternatively, you can make it work with any nut butter you like (yes, including sunflower butter, for those with a nut allergy).
And if you like your milk to be a bit sweet, you can add a sweetener of your choice, such as dates, maple syrup, honey or a dash of vanilla extract. If sweetened, a little salt can help increase the flavor of the milk.
