Jeera Khar (also known as Jeera Khair or Carum Carvi) refers to the dried seeds of the caraway plant, which are small, crescent-shaped, and brown with a distinctive earthy and slightly sweet aroma. Carum carvi is native to Europe, North Africa, and Western Asia, and its seeds are commonly used as a spice in baking, breads, and savory dishes. The seeds are valued for their essential oils, which contribute to their strong flavor and aroma. Jeera Khar is available as whole seeds or ground powder and is often used in spice blends and culinary preparations.
