We have a few jars of various powders on the kitchen shelf that promise us eternal life. They contain about a thousand tons of kale and everything else too. They're great in our morning nutribullets. They are, however, expensive.
We also have a permanent collection of avocados in the fruit bowl. They are replaced with fresh ones, obviously, but they come with a free stone inside. Over the week, these build up into a pile, albeit one that rolls about the place, and as I won't be creating an avocado farm in the garden, I roasted them this afternoon for about an hour and then pulverised them in the blender.
Apparently the stones have more nutrients in them than the avocado itself and will also guarantee eternal life. Maybe I'll be able to keep my band on the road until we're in our hundreds as well. I'd have to get it back together though. We were called 44 stone after our combined weight. As Bee says, if we reform, we may have to up that number...
You can dry the stones out on the window sill for a week or two before blending if you prefer, but roasting does help bring out the nuttiness. 160c is hot enough. Blitz them into a powder then store in a jar, adding a tablespoon to your smoothies or sauces as you want.
