Coriander is one of the oldest of herbs and spices. The fruit of the coriander plant contains two seeds which, when dried, are the portions used as the dried spice. When ripe, the seeds are yellowish-brown or tan in colour with longitudinal ridges. Coriander seed has a warm and subtle flavour with a slight citrus hint. It has an aromatic scent that is soothingly warm, nutty, slightly fruity, and complex. Coriander seeds are available throughout the year, in whole or in ground powder form.
