Icy Blue Razz
I genuinely thought putting a "clear" protein in a milky Creami base would be a disaster, but I was dead wrong. This creates a vibrant, tangy sherbet that tastes exactly like those bright tubs of frozen sherbet you’d grab as a kid. It’s a total genre-bender that delivers a clean, zesty punch without any of the typical protein aftertaste.
