I'm not sure if fruit smoothies are MEANT to be foamy and sludgey but i just love it that way for some reason. Chewy chunks of apple and a strange thick but light consistency. I guess it reminds me that it's really freakin' healthy. For this one i used 3 small red apples, 2 cups of spinach leaves and half a cup of water (with a bit more added at the end if you so wish)
I tried blending the water and spinach first, and adding the apple after to push it all down, but it took a fair bit of shaking of the blender to get it all blitzed. The PULSE function proved very useful lol!
