Almas golden caviar - a lavish folly at $11,000/lb for food fetishists

Sure, you can buy the whole 1kg tin(that would be 35 oz.)of this albino sturgeon caviar which comes with a 24K gold can. A keepsake which guarantees your bragging rights forever, that you've spent an obscene amount of money on fish roe. The kind of money you could pay for a year's tuition with.

Chowhounds wouldn't fall for such profligacy, or would they?

Almas is an extreme example, but conspicuous consumption goes on all the time in varying degrees, and chowhounds, too, are only human.

Example of what you think is conspicuous consumption, not a quest for good food.
