Agave nectar is a sweet syrup derived from the agave plant, primarily found in Mexico. It is produced by extracting the sap from the plant's core, which is then filtered and heated to convert its natural sugars into a liquid form. Agave nectar is often used as a natural sweetener in various foods and beverages. This sweetener is known for its low glycemic index, meaning it has a smaller impact on blood sugar levels compared to traditional sugars. It is available in different varieties, ranging from light to dark, with darker versions having a more robust flavor.
