Notes
*Freeze the other quarters of green apple for future smoothies- replace 2 of the ice cubes in the smoothie recipe with 1 frozen green apple quarter**So I’ve discovered ice cube size can vary! These are made with ice-cube trays purchased online. If you make your smoothie and it seems too watery/liquidy and not thick don’t worry, you aren’t crazy! Your ice-cubes are just smaller. Either add more ice-cubes or buy some trays online to use. The point is your smoothie should be kind of hard to blend- that’s how thick it should be.
