Original Receipt in 'Acetaria: A Discourse of Sallets' by John Evelyn (Evelyn 1699)65. Succory, Cichorium, an Intube; erratic and wild, with a narrow dark Leaf, different from the Sative, tho' probably by culture only; and for being very bitter, a little edulcorated with Sugar and Vinegar, is by some eaten in the Summer, and more grateful to the Stomach than the Palate. See Endive .
