Tu BiShvat (Hebrew for the 15th day of the Hebrew month of Shvat) is the new year of the trees.
This recipe is adapted from the King Arthur Flour Cookie Companion's recipe for Bakery Date Squares.
Here is the quintessential Jewish question: How do we emulate God? We are told that we were created by God. We are told that we have a divine spark within us.
"Tu" (the Hebrew abbreviation of 15th) in the month of Shvat was set (Hillel's opinion generally overrules Shammai's) as the beginning of the tithable year for tree fruit: Calculating the tithe on fruit starts again for fruit that sets after that date.
While my neighbors were putting their Christmas trees to the curb, in what seems like a ritual of replacement, I was preparing to plant for Tu BiShvat.
