Sweets that have been processed from haws, the fruit of the hawthorn tree, are widely available in New York, but before Beijing I'd never tasted "tanghulu" (Y5), haws rolled in hot syrup. Same nice applelike flavor, plus two or three little applelike seeds in each haw. Also available was an intriguing oval reddish fruit ("fruit" in the botanical sense); I never did manage to try sugar-dipped tomatoes.
