Acetaria: A Discourse of Sallets is a 1699 treatise by the English writer John Evelyn on salads, vegetable cookery, and gardening. It discusses the cultivation and preparation of salad plants, includes a catalogue of 82 ingredients, and gives a nine-part method for dressing a salad. The work also draws on classical and medical authorities, including Galen, in its discussion of diet and health.
The text grew out of material Evelyn had assembled by the late 1670s and was connected to his larger horticultural project Elysium Britannicum. It has often been described as the first standalone book devoted to salads. Later writers have discussed it in relation to the history of cookery and vegetarian writing.
