The spice most often called the "queen of spices" is cardamom.
Cardamom, particularly green cardamom ( Elettaria Cardamomum Maton), is highly prized for its aromatic flavor and is often referred to as the "queen of spices." Its unique and complex flavor profile makes it a versatile ingredient in both sweet and savory dishes.
