Protein in your coffee
Most protein powders are built for a shaker of cold water. Drop one into hot coffee and it seizes — the whey denatures, clumps against the side of the cup, and you pour the whole thing away. The powder is fine. The temperature is what ruined it.
These are the pieces we have written on doing it properly: which powders actually dissolve, the warm-milk method that makes a smooth protein cappuccino, and the drinks we make in the mornings here.
The short version, if you read nothing else: warm milk, never hot. Whey sets above roughly 70°C. Build the protein into milk at drinking temperature first, then bring the espresso to it.
