Roy G. Biv Smoothies

by Nick

I’ve had a few requests over the last few weeks for some smoothie recipes because I let it slip that Betsy and I generally just have a big smoothie for breakfast everyday. Turns out our daily smoothie recipe is a mix between yellow, red, and indigo, but that’ll make more sense to you later.

Smoothies can be so varied I really struggled for awhile on how to present a wide spectrum of recipes in one post. That was, of course, until I saw a guy riding a bike last weekend with a rainbow sticker on his backpack. When I saw the rainbow I thought, now those would be some awesome smoothies!

Anytime I think of a rainbow, I can’t help but think of the mnemonic device for remembering the order of the colors: ROY G. BIV!

After some tinkering, I present to you, the ROY G. BIV Smoothie Team!

Each of the recipes I used are below, but before that, there are a few quick notes on smoothies that I think are important.

First, smoothies are all about balance. You want to combine some sweet with some bitter. You want to make sure that your acids are balanced. Really if you do that and taste as you mix, you can’t go wrong. These recipes should all be seen as jumping off points. Mix and match and find your own, well, rainbow. (I should be a motivational speaker with lines like that!)

Second, whenever possible try to use frozen fruit instead of fresh. I usually use mostly frozen fruit just because it’s easier but some fresh fruit is fine. The thing to remember is that if you use fresh you have to throw in some ice which waters down the smoothie a bit.

Third, keep some juice (orange, apple, cranberry, pomegranate, etc) on hand as well as some milk or yogurt. Those can smooth out your smoothie…

So let’s take a trip through Roy G. Biv!

All of the smoothie recipes in this post are adjusted for 2 Cups of smoothie which is about enough for one big serving. The cups in this post hold about 1 cup of liquid so I halved the recipes for this post because I didn’t need 7 cups of smoothies floating around.

The Red Smoothie. This is pretty straightforward. After I tasted it, I added a pinch of sugar because it was just a bit too bitter for my tastes. I also used frozen raspberries, but if you use fresh you’ll need to add some ice.

Other options: beets?

The Orange Smoothie. This one is just like a shot of vitamin C. It’s refreshing and delicious and if you’re afraid of flavor mixing, this is the one for you! If you can’t find clementines, you can use any orange-like fruit. Tangerines for example would be awesome.

For those that need a shot of Vit. C.

The Yellow Smoothie. This one seriously tasted like a milkshake. The banana and milk made it really creamy and the mango was nice and sweet. If you served me this blind, I’d guess there was ice cream in it.

Very sweet actually.

The Green Smoothie. Ok. I was a little worried about this one. Basically I just picked out a bunch of green stuff and threw it together! At first, it tasted kind of funky (some would say it tasted healthy), but then I added a pinch of sugar and a tiny pinch of salt and that totally mellowed out the flavors. The sugar and salt are not optional in this one if you want it to taste decent.

Shockingly, green was pretty good!

The Boozy Blue Smoothie. Ok. It turns out that there are no really blue foods. Sure there are some flowers and stuff, but there’s just nothing that pops with blue color. Blueberries are totally mislabeled. They are purple, people.

So I figured if I couldn’t find a food that was blue, I might as well making something with booze in it! This was actually really tasty and I could imagine sipping a few of these on a beach somewhere.

Maybe not for breakfast.

The Indigo Smoothie. This one is a really basic one, but the Pomegranate juice has huge flavor. Sometimes Pomegranate juice can be a bit bitter though and so the yogurt smooths it out nicely.



The Violet Smoothie. Ok. So this one was maybe my least favorite of the seven. It was pretty strongly flavored. I thought about maybe adding some plum to the mix which I think would keep it pretty violet but might mellow it out a bit.

In other news, I’m not entirely sure what the difference is between violet and indigo. It’s possible I’m slightly colorblind.


Violet = Indigo – Yogurt…

The Equipment. Of course, to make smoothies you’ll need a good blender. Now you could spend hundreds of dollars on a blender, but I’m not sure that’s really necessary if you’re just getting into the smoothie thing. I’ve had this really excellent professional Oster model blender for almost a year now and I use it almost daily. It’s nothing fancy but it has all metal parts and only two speeds: pulse and GO. What else do you need?!

Mine performs just like it did on day one!


Roy G. Biv!

Day to day though Betsy and I, surprisingly, don’t make our smoothie choice based on color. Like I said at the beginning of the post, we normally do a mix between the indigo, red, and yellow varieties.

Just one more…

It’s very possible that I had more fun making and writing this post than any post in Macheesmo history. There were moments when I had to just stop, look at my counter full of crazy colors and ingredients, and laugh out loud. It was so much fun.

I hope you all try some of them out and pass along this post to your friends. Also, leave a comment obviously and let me know which one you want to try or if you happen to know a blue food that I missed!
