Chocolate and ice cream
Temperature contrast rather than flavour contrast — and cold suppresses chocolate's aromatics, which is why sauce works better than a bar.
Chocolate with ice cream is a temperature and texture pairing above all. What is worth knowing is that cold substantially suppresses aroma perception, so a good bar eaten with ice cream gives up much of what makes it good.
That is why chocolate sauce works better than chocolate pieces: a warm sauce releases its aromatics before the cold shuts them down. It is also why chocolate ice cream needs a higher cocoa content than the equivalent bar would to taste equally chocolatey.
The principle
Cold suppresses aroma. Use warm sauce rather than cold chocolate, and expect to need more chocolate for the same intensity.
Pairings
Warm dark chocolate sauce over cold ice cream gives both the temperature contrast and enough aromatic release to taste of chocolate.
For example: warm 70% dark sauce over vanilla ice cream
Flakes provide texture contrast without needing to be tasted in detail, which suits a cold application.
For example: chocolate flakes over ice cream
Serving
Let the ice cream soften for a few minutes. Straight from the freezer it numbs the palate to the chocolate entirely.
