When cooked properly, Brussels sprouts taste fantastic, even addictive. While Brussels sprouts can be bitter raw, cooking them at a high temperature ensures they have a rich, caramelized flavor, and a tender, satisfying (but not mushy!) texture. Do not over-crowd your pan, which will lead to uneven cooking.
Throwing some garlic in the pan about half way during cooking gives another boost in flavor. The nuttiness of the garlic is a delicious combination with the sweet/sour vinegar and the crisp sprouts.
