Yeah, online recipes are a pet peeve of mine. More than that, really: online recipes are a significant source of pain and struggle in my life. I hate them. These days I print them. And sometimes when I invest time wading through seventeen advertisements and clicking through five popup videos and such, I write up my result in hopes that other humans may some day benefit from my labor.
Every few years I get on a Star Wars kick and invite some people over to watch, which has now twice resulted in attempts to make blue milk. The version that Disney makes and sells for $19 a cup is quite good! This base recipe is not quite as tasty, but it's a solid base for customization.
I prefer the full-liquid version that you can chill or put over ice, but I think Disney's is more like a slushy. Homeade slushies tend to separate too much for my liking, but if you poured this into one of those icee machines it would probably turn out pretty well.
This version is super simple and dairy-free, and in a small sample of taste-testers, most people say "wow this is actually pretty good!" It's also a very safe and versatile base, so you could start with this ratio in the blender, and then add ingredients and taste test until it's just how you like it.
The only catch is that if you drink this before watching Andor, there will be part of you that dies a little more with each sip. So it's probably best to watch every episode of Andor before making this at home.
Cheers!
