Tu BiShvat (Hebrew for the 15th day of the Hebrew month of Shvat) is the new year of the trees.
Derived from central Europe, the popular kichlach (Yiddish for "cookies") are to be found in many of the packages prepared by parents for their children serving in the Israeli military.
My husband introduced me to techina (tahini), a staple found in most Israeli kitchens, as soon as we made aliyah in 1992.
Jewish communities around the world marked the "new year for the trees" last week with tree planting ceremonies and seders that celebrate Israel's seven species (wheat, barley, grapes, figs, pomegranates, olives and dates if you are keeping track!).
