Korech - The Sandwich
While the English Earl of Sandwich is generally credited for inventing the snack of his namesake, Hillel may have originated it two thousand years ago by combining matzah, a slice of paschal lamb, and a bitter herb. Jews no longer sacrifice and eat the lamb, so the Passover sandwich is only matzah, charoset, and a bitter herb now.
Each person receives some bitter herbs and ḥaroses, which they place between two pieces of matzo.
All say in unison: “Kein ah-saw Hillel” and eat the sandwich reclining.
