I believe there's another thread on that floating around somewhere.
But anyway, I was actually thinking about this today after you mentioned it in chat. I came up with some combinations:
Shupu - greasy, fried foods. Also, gourmet cheeses.
Young sheng (bitter) - something salty, I think.
Japanese greens - definitely sweets, chocolate, etc.
Roasted tgy & yancha - strawberries, raspberries, blueberries.
Whites - melons like canteloupe & honeydew.
Blacks (malty) - breakfast foods! Scrambled eggs, bacon, potatoes...
I've tried both the Shupu combinations and liked them, but those seem to be pretty well known. Everything else is just me guessing.
It's also worth mentioning that I'd never do this with any kind of premium tea, or any tea that I want to pay specific attention to.
