With the rise of veganism and lactose intolerance, nut milks are getting popular (also, they're delicious in their own right). But they cannot be found package-free, and involve mass-scale agriculture and production, so they are quite damaging to the environment. Happily, they are the easiest thing to make at home from bulk-bought nuts – all you need is a blender. This same method also works for making your own coconut milk rather than buying it tinned! I make cashew milk for my morning tea regularly, in small quantities adapted to my personal consumption: other than the overnight soak, it genuinely takes only a few minutes.
