For over a century, American Jews have eaten American Chinese food on Christmas. This pastime has evolved to a near-holy tradition, parodied on Saturday Night Live, analyzed in academic papers, and reaffirmed by Supreme Court Justice Elena Kagan.

Perhaps the foremost expert on the practice is Rabbi Joshua Eli Plaut, PhD, executive director of American Friends of Rabin Medical Center, rabbi of Metropolitan Synagogue in New York, and author of A Kosher Christmas, the premier (and only?) comprehensive study of what Jews do at Christmastime.

I spoke to Plaut about Chinese food on Christmas, and why he used to sit on Santa Claus’s lap.

I knew about this tradition (and have partaken of it myself) but just assumed was just that. I didn’t realize there’s an actual, “logical” reason for it.
