Cardamom as a small finishing note
The idea
Cardamom has a strong, distinctive fragrance, so a little can shape the character of a sweet or spice mixture. The goal is not to make every ingredient compete with it. In a restrained combination, you can notice the aroma while still recognizing the main food underneath.
A practical next step
If you are trying cardamom at home, begin with a small amount and compare the result with an unseasoned portion.
