Gold, world's most expensive food

I'd be reluctant to count gold as a food, only because it adds nothing to the taste. It's purely decorative. I once had a drink with gold flakes in it and it was a huge letdown.

Using a per-pound basis to measure the expensiveness of food strikes me as odd; a per-serving metric would be better. After all, high-end white teas can cost $1000+ per pound, but since a serving is 2-2.5g, they're still affordable.

Also, I don't know if foie gras will be a French delicacy for much longer, because I believe it will be banned in the EU soon. Good riddance to it; blech!
