In a bowl, add 3 cups of water, raw almonds, vanilla bean, star anise, cardamom pods and stir. Cover with plastic wrap and transfer to the refrigerator overnight.
Strain the almonds, discarding the water, vanilla bean, star anise and cardamom pods. Transfer the almonds to a blender and add 3 cups of water. Blend until very smooth, 2-3 minutes. Strain the almond and water mixture using a cheesecloth and strainer. Transfer the almond milk to a glass container and keep in the fridge for up to 3 days.
To make the almond banana milk, add 1 1/2 cups of almond milk to the well of a blender. Throw in 2 bananas and a pinch of salt; blend until nearly smooth. Divide between two glasses and serve immediately.
