Celery seed is the seed of plant closely related to celery, cultivated specifically for its aromatic, flavourful seeds. It can be found as an ingredient in spice mixes all over the world. Like other plants in the Apiaceae family, celery seed has a strong celery like flavour and aroma, with a faint hint of spiciness. Celery seed is particularly useful when you want to add a celery flavour to a cooked dish when the crispy crunch of the actual vegetable is undesired. Sprinkle on salads for a fresh summary taste, or add to potato dishes.
