(n) A word meaning "bitter," marror is eaten at two specific points during the Passover Seder, and its purpose is to commemorate the many bitter times Jews have endured—especially throughout slavery in Egypt. But what is marror exactly? It is raw horseradish root and/or romaine lettuce (both are acceptable, although we're never given the less caustic lettuce option, even as children). Nowadays, we're sitting (or, rather, reclining) pretty, so at the very least we can choke down a couple pieces of eye-watering horseradish for our ancestors' sake! The 1st time it's consumed during Passover Seder, marror is dipped in charoset (a sweet spread made of some combination of apples, cinnamon, raisins, honey. and nuts—but every family has their own charoset recipe). The 2nd time, it's bookended by two pieces of matzah to form the Hillel sandwich.
