I somehow found a packet of "full cream" pasteurized milk in the fridge. It was in the bottom section, not the freezer. (My fridge has an ice-making compartment at the top, where I generally keep pasteurized milk.) I have no idea how many days ago it was bought.
The milk wasn't frozen, as expected. It was a slightly cool liquid.
When I poured the milk into the pan, I saw it had a yellow tint to it, but no lumps. As the milk was being heated, the corners began to turn a bright white. Slowly and slowly, the white part was increasing and centering the yellowish part. After I took it off the stove, it had again turned a creamy yellow colour. I shook it, and the cream collected on top. The milk below, however, was white.
I find this very odd—pasteurized milk is usually pure clean white. I can't afford to take risks in such matters.
Is the milk spoiled? Should I drink it?
The smell was perfectly alright. I took a sip: the milk tasted very creamy and delicious.
