Poppy seeds were widely used in nineteenth-century Russia, both as seeds and pressed into oil. The seeds were cultivated mostly in Ukraine, Saratov, and Voronezh; they came in three or four colors, depending on the variety of the plants, white, brown, blue, or gray. Molokhovets decorated pastries with “variously colored poppy seeds” and, when making wafers, preferred to use gray rather than white seeds (#3084).
