Answer 2

Answer:

Does your expensive olive oil perhaps contain slightly more of the higher-freezing-point fatty acids (e.g., palmitic acid) than your cheaper olive oil? That's unlikely, but who knows? The amount of palmitic acid in olive oils can range from 7.5 percent to 20 percent.

Forget about cloudiness and buy the tastiest olive oil. As long as it's extra-virgin, you won't be disappointed. If it turns cloudy in the fridge, just warm it up, and it'll become clear again.
