Tu BiShvat, called the "New Year of the Trees," falls at a seemingly incongruous time of year.
Tu BiShvat is a minor festival whose provenance dates only to the time of the Second Temple. However, the kabbalists who clustered around the great fifteenth-century mystic Isaac Luria of Safed placed great weight on the holiday, creating new festivities, gatherings at which hymns were sung, fruit (particularly carob) was eaten, and four cups of wine were taken (as in the Passover seder).
The use of sherry vinegar, cumin, and oranges speaks volumes about the Iberian influence on the cooking of South America.
It is life we want, no more and no less than that, our own life feeding on our own vital sources, in the fields and under the skies of our homeland, a life based on our own physical and mental labors; we want vital energy and spiritual richness from this living source.
