Every year, I hold an epic, table-groaning, far-too-many-chairs-stuffed-into-the-house Passover Seder. There’s something about sitting down and lighting the candles, about creating a moment that reaches back through time and out to everyone else who is doing, and has done, the same. And, of course, making variations on the same food. But recently I learned that Passover isn’t the only Seder holiday. Within the Sephardic tradition—the Jews of the Iberian peninsula, and post-1492 expulsion, the surrounding areas—there’s a second Seder holiday: Rosh Hashanah, the Jewish New Year.
