Alecost (costmary)

Alecost, also called costmary, is a fragrant herb whose leaves are used as a seasoning. The leaves are elongated and softly textured, with a distinctive aromatic, somewhat mint-like and balsamic flavour. It is not the same culinary herb as common mint, despite a resemblance in some descriptions; taste and aroma can vary with the plant and growing conditions.

The leaves may be used fresh or dried, in small amounts to flavour foods and infusions. They are generally the relevant culinary part, rather than the plant’s roots or flowers. Dried leaves are more concentrated and less tender than fresh ones, and products sold as costmary may consist of whole leaves or crumbled herb.
