I’d read about people using avocado pits in green smoothies, so when my wife was about to throw away an avocado pit tonight I asked her to keep it so I could blend it and see how bad it was.
I blended it up with some fresh blueberries a few cherries and some shiso leaves from our garden, along with a generous amount of water and ice. I love shiso, to the point that it represents the majority of our garden at this point in the season, and even enjoy blending shiso leaves with just water and ice, but no amount of shiso or fruit was going to make that avocado pit taste good enough to make it worth drinking, even it is filled with antioxidants, potassium and fiber. It was way too bitter and unpleasant for me to try using again any time soon.
My other recent experiment, which worked out much better, was putting sweetened condensed milk and caramel sauce on top of blended coffee ice cubes. That turned a quirky summer bowl of (literally) ice coffee into a tasty treat, and I’ve updated that recipe to encourage anyone who tries blending coffee ice cubes to put sweetened condensed milk on top.
