Chicory Root is commonly baked, ground, and used as a coffee substitute and additive, mainly in the Mediterranean region, although its use as a coffee additive is also very popular in parts of Southeast Asia and America. The root gained its majority of popularity as a coffee substitute in poorer economic areas during the 1930's. Craft brewers use roasted chicory to add flavor to their stouts and other styles brewed with coffee and roasted malts. Chicorium intybus. 1 oz.
