Did you know about the Seven Species (SHIVAT AMINIM) mentioned in Deuteronomy 8:8? KHITAH (wheat), SEORAH (barley), GETEN (vine), TE’ENAH (fig), RIMMON (pomegranate), ZAIT (olive) and DVASH (date honey). Date honey is (also?) known as SILAN; the date fruit itself is TAMAR, and the palm is DEKEL TAMAR. Tamar is just tree in Arabic, I think, from where we get our Tamar-e-Hind or Tamarind.
Three foods are mentioned often together in the bible: DAGAN (cereal, either wheat or barley), TIROSH (wine), and ITZHAR (olive oil). This was the staple food of the people. These were the offerings made in the Temple, and these are the foods used in the Sabbath meal.
