Root chicory (Cichorium intybus var. sativum) has been in cultivation in Europe as a coffee substitute
. The roots are baked, ground, and used as a coffee substitute and additive, especially in the Mediterranean region (where the plant is native), although its use as a coffee additive is also very popular in India, parts of Southeast Asia and southern United States, particularly in New Orleans. It has also been popular as a coffee substitute in poorer economic areas
, and has gained wider popularity during economic crises such as the Great Depression in the 1930s. Chicory, with sugar beet and rye was used as an ingredient of the East German Mischkaffee (mixed coffee), introduced during the "coffee crisis" of 1976-79.
