compoter

Compoter is a rare culinary verb, related to compote, meaning to cook fruit down slowly until it softens into a compote-like texture (des pommes compotées). It's mostly seen in recipes as the past participle adjective compoté(e) rather than as an active verb.

• Faites compoter les pommes à feu doux pendant vingt minutes. — Cook the apples down slowly over low heat for twenty minutes.
• Ces oignons compotés accompagnent bien la viande. — These caramelized-down onions go well with meat.
• Les fruits ont compoté toute la matinée. — The fruit has been stewing down all morning.

Compoter appears almost exclusively in recipes, usually as compoté(e) describing softened, slow-cooked fruit or vegetables — there's no common everyday mistake since general learners will rarely need the active verb form.
