Chocolate and dried cranberry
Almost always sweetened, and the sweetening is the thing to know about. A raw cranberry is too acidic and too tannic to dry palatably, so what you are pairing is a fruit that has been rebalanced in a factory.
Cranberries are extremely high in acid and carry noticeable tannin, and they contain very little sugar of their own. Dried unsweetened, they are close to inedible — so essentially all commercial dried cranberry has been infused with sugar syrup during processing.
That matters for the pairing in two ways. The sweetness you taste is added rather than concentrated, so it sits differently on the palate — cleaner and less caramelised than a raisin's. And the tannin survives, which makes cranberry the dried fruit most likely to compound a dark chocolate's astringency in the way walnut does.
The result is a fruit that works better with milk and white chocolate than the assumption "sharp fruit needs dark chocolate" would suggest.
The principle
Sharp and tannic. Its acidity suits a sweeter chocolate, and its tannin makes very dark chocolate a harder match than it looks.
Pairings
The most useful thing cranberry does anywhere. White chocolate has no acidity and no bitterness, and cranberry supplies both — a genuine rescue of a chocolate that is otherwise structurally flat.
For example: dried cranberry and pistachio in white chocolate
Milk chocolate's sweetness and low bitterness give the cranberry's acidity somewhere to go without meeting competing astringency.
For example: cranberry in milk chocolate
Commonly recommended, and frequently disappointing
Cranberry with a very dark chocolate. Both carry tannin, and the astringencies add rather than balance — the same mechanism that makes walnut and dark chocolate unreliable.
Serving
Check the ingredient list. Cranberries sweetened with apple or pear juice concentrate taste noticeably different from ones sweetened with sucrose, and the juice-sweetened versions are generally softer and less sharp.
