The inspiration for this salad comes from the Seder plate: Although the "bitter herb" is often horseradish, in the Sephardic (or Mediterranean) Jewish world, it can be an assertive green, one with bite. We chose dandelion greens, which are at their peak this time of year. (Please note: for Ashkenazi Jews, the mustard in this recipe is not considered kosher for Passover.)
Appetizing. You think you know what it means: tasty, enticing you to eat. But in the early 20th century, among the Eastern European Jewish immigrants living on New York City's Lower East Side, appetizing was more commonly used as a noun, referring to the delicious array of foods -- smoked fish, cream cheeses, cold salads -- that were traditionally eaten with bagels. Back then, there were upward of 30 "appetizing" stores in the neighborhood. Today, only one remains: Russ & Daughters.
