Chazeret

Bitter Vegetable (often lettuce) is often used in addition to the maror as a bitter herb. The authorities are divided on the requirement of chazeret, so not all communities use it. Since the commandment (in Numbers 9:11) to eat the paschal lamb "with unleavened bread and bitter herbs" uses the plural ("bitter herbs") most seder plates have a place for chazeret. Some use a green vegetable (such as lettuce - as long as lettuce is not also used for karpas), some use the green top of a bitter herb, while some use a second bitter (such as raddish) for the chazeret.

Lettuce in the produce section. Avoid sweet lettuce if possible.
