I don't think you can flash freeze leafy greens and still maintain the texture. Have you eaten flash frozen lettuce for salad?

I mean like, why not? I think the issue with leafy greens is that they're fairly stable, travel well and grow well/quickly in greenhouses, so it's not worth flash freezing them.

Because they're mostly water, and water expands when frozen, destroying the structure of the plant.

You know what else destroys the structure of the plant? Chewing.

That’s a part of the experience though. Freezing will preserve the nutrients, but risks the “mouthfeel”.

But if you’re going to blend it, who cares.
