To caramelize something means to cook it slowly over low heat until it turns golden brown and develops a sweet, sticky flavor.
When we talk about caramelizing food, we usually think of cooking sugar or onions. If you're making a stir-fry, you might need to caramelize the onions before adding them to the dish - that's when they turn from raw and crunchy into soft, sweet, and deliciously brown. Some people also use this word for other foods like bell peppers or mushrooms, which can get a similar flavor if cooked slowly over low heat. But caramelizing is especially great for sugar because it melts and turns into a syrupy, golden liquid - that's what makes caramel candies so tasty!
