Why Cauliflower has turned bitter in curry?

Cauliflower can turn bitter in curry due to various reasons, including overcooking, which can release bitter compounds in the vegetable. Additionally, if the cauliflower is not fresh or has been stored improperly, it may develop a bitter taste. The bitterness can also be enhanced by certain spices or ingredients in the curry that interact unfavorably with the cauliflower. Lastly, some cauliflower varieties are naturally more bitter than others, especially if they are mature or past their prime.
