i've been watching old episodes of Gordon Ramsey's Kitchen Nightmares
(USA edition). More than once I've heard him tear into a chef for
putting "hot" anything into a cold refrigerator. He claims it makes the
item "sour". True?

I put semi-hot soups into the fridge to cool faster. Letting the
soup/whatever cool on the range, then putting in fridge, causes hot item
to spoil sooner, IME.

What say the brethren?
