The carob tree or its edible pod, which has a sweet pulp used as a chocolate substitute and livestock feed.
From Spanish algarroba, which came from Arabic al-gharrubah (the carob pod). The word traveled along Mediterranean trade routes where the carob tree was cultivated.
Carob pods are so sweet and nutritious that they sustained entire civilizations around the Mediterranean, and today they're making a comeback as a natural chocolate replacement that doesn't require shipping cacao across the world.
