According to Dictionary.com a smoothie is "a thick beverage of fruit pureed in a blender with ice and milk, yogurt, or juice". Fruits tend to be sweeter than vegetables, so that would assume smoothies should be sweet. But why couldn't a smoothie be savory? Today I performed an experiment and made a vegetable smoothie.
It all started with a head of cauliflower. One of my projects this morning was to cut off the florets and blanch them for crudités (because I think they taste better that way). I usually just toss the core in the stock bag, but today I took a good look at it. It didn't seem any different than the stems of the florets, which I eat all the time. I decided to try cooking it and see what happened, then eat the results of my test for lunch.
I chopped up the cauliflower, but there wasn't quite enough for a whole meal, so I dug around in the vegetable drawer to see what else I could find...a small carrot, a quarter of a red onion and a couple of stalks of celery. I threw everything in a pan, added water to cover and a beef bouillon cube for flavor, and put the pan on the stove.
When the vegetables were done, I whizzed them into a puree with my immersion blender and added a cup of yogurt. If I'd put the mixture into a bowl I probably could have called it soup, but instead I poured it into a cup and drank it. Not bad at all!
