This is cursed, and every added detail is more cursed. Holy moly.

Usually if I throw whey protein into something and it comes out chalky the problem is not enough liquid, you may have just reduced it too far. I'd probably try adding... chicken broth? Man that feels gross to suggest, but I imagine adding milk to Chinese food would be worse.

God speed on that diet, my man, you need it.

homemade chinese food and whey soup 😭

I make hot, savory protein shakes all the time. I found that the trick is to mix the whey into enough cold liquid, about one scoop whey to at ~120ml/4 ounces cold water or stock. Once blended, then add it to your hot ingredients. The result is a much smoother shake/soup.

Just drinking the whey separately omg why would you add it to soup.
