Almond milk is very straightforward to make at home,and it goes with my general ethos of if you can make it then you should as you will know all of the ingredients that went into it and there will be no additives to prolong the shelf life. It does take a little bit of forward planning as the almonds need to soak overnight, but if you use a lot of it then it should be easy to get into a routine.
Ingredients
Almonds and water
You will also need: A beaker to soak the almonds in overnight, a blender to blitze the almonds, a sieve and bowl and a muslin cloth as the sieve will not be fine enough to extract the milk from.
