chocolate (see Karttunen)
"...chocóllatl, is made with grains of póchotl and cacáhoatl in equal quantities, and they say that it puts on extraordinary amounts of weight if it is used frequently. Both grains are mixed together, put in a vessel, and stirred with a wooden whisk until the fatty part floats and is airy. That part is then skimmed off and set aside. Added to the mixture then is a handful of the aforesaid Indian grain that has been softened." (Central Mexico, 1571–1615)
San Lucas Tepechocotlan [i.e. Tepexocotlan] is a place name mentioned in one of the maps of the Relaciones Geográficas. The glyph shows a ceramic pot sitting on top of a tepetl (hill, mountain), with a xocotl plant coming out of the pot. The colors used in the glyph are blue, tan, and brown. This has nothing to do with chocolate. https://utlibrariesbenson.omeka.net/items/show/26#lg=1&slide=0
