Ok, now that I’ve gone on and on about how great they are let’s get down to practical matters – do you need a special blender to make them? In a word, no. BUT, a high powered blender like a vita mix or something similar will open up a whole new world of ingredient options to you. For example, when we were in CT I really, really, REALLY missed my Vitamix and will never leave it behind again when we go on an extended trip like that. I had a typical blender at the house we were renting but it could only really handle organic baby spinach and soft fruits like bananas. Of course just those two things and water make an excellent smoothie but you’ll want some variety if you’re going to make it a habit. With my vitamix, I can use kale, pineapple, whole peeled clementines, grapes and other fibrous fruits and greens and get a smooth and creamy consistency. A normal blender would never be able to handle that stuff without an unpleasant pulpy consistency. I know because I’ve tried! But papaya which I love and is SO GOOD FOR YOU would blend just fine in a normal blender–as would any other soft, non fibrous fruits and greens (organic baby spinach, romaine, butter or other soft lettuce). You’re making “the face” aren’t you?!?! Stop it! Give it a chance, you’ll be amazed at how the fruits will neutralize and enhance the flavor of the greens. When you first start out, you’ll want to use a higher ratio of fruits vs greens, but once you get the taste for it, you’ll be able to use much less fruit and you’ll come to crave that green flavor–I promise! So give them a try with any normal blender using easily blendable stuff before you start worrying that you have to upgrade. Which if you love cooking I suggest you start saving up anyway because my vitamix is the single best purchase I’ve ever made for my kitchen and I use it almost daily.
