Use all your senses.
What color is the chocolate? Is it glossy, matte, dark, light? Bring the chocolate up to your nose and inhale deeply. What aromas do you pick up? Break the piece of chocolate in half. Does it snap? How does the chocolate feel as it melts on your tongue—creamy, velvety, or chalky? Finally, how does it taste?
Pair it up.
The complex flavors in chocolate only increase when paired with wine, beer, coffee, tea, cheese, dried fruit, salty snacks, and nuts. The only limit to what makes a great pairing is your imagination!
