Ground

Toasted
Whole coriander seeds that have been lightly toasted to enhance their nutty, warm flavor before being used whole or ground.
Whole seeds
Dried coriander seeds that can be used whole or ground into a powder. Whole seeds retain their flavor longer than ground coriander.

Blooming: Blooming ground coriander in a fat, such as oil or butter, is a common technique to unlock its flavors. Add the spice at the beginning of the cooking process, allowing it to cook for a minute or two until it becomes aromatic.
Toasting: To enhance the flavor of ground coriander, toast it lightly in a dry skillet over medium heat until it becomes fragrant. This process releases the essential oils and should be done just before adding to your recipe to maximize flavor.
Mixing into Marinades: Ground coriander is often mixed into marinades to impart its flavor to proteins. The spice works well in both dry rubs and wet marinades, and benefits from some time to infuse into the meat or vegetables.
