Make sure you have a slow juicer, preferably a Hurom juicer. Slow juicers retain more nutrients than the average juicer.
Measure a cupful of almonds (in Melbourne, 500g of almonds cost 10 dollars)...
...and soak them in a litre of water (preferably filtered) overnight, in the fridge. The almonds will swell and release their juices.
Set up the juicer. One container will collect the almond meal; one container will collect the almond milk. Plug it in and switch it on.
Pour the almonds into the juicer.
Let the magic happen.
Bottle the almond milk.
Season the almond milk with a teaspoon of agave syrup or honey, and a pinch of salt.
