Kiwi starfruit and Almond milk??? It's separating because even the drink knows this is a cursed combination that should never be. I don't know why I'm fine with Coconut milk being used but not Almond, but I find this revolting.

As to an actual solution, I don't think there is one, Almond milk simply floats above other cold liquids rather than mixing and there's nothing we can really do without something like an emulsifier to stabilize the mixture

The fat content in our almond milk doesn't play well with the citric acid in our refreshers. There's a reason Starbucks went with coconut milk for these.
