Ajwain, or ajowan, is used in Middle Eastern and Asian cuisine, for its strong fragrance and ability to blend with complex spice mixtures. Slightly bitter or bright, with a bracing aroma very reminiscent of thyme, it lends a subtle tangy fresh flavor to many dishes, though it is most often used with lentils, beans, and legumes (it is believed to help reduce flatulence). Can easily overpower a dish, so use lightly, and experiment! This unusual spice can be a sneaky substitution for thyme or savory in European dishes, but is usually used in curries, dals, soups, and stews.
