Agave nectar is a sweet, sweet syrup that comes from a plant called agave. Just like honey comes from bees, agave nectar comes from agave plants.
Agave plants grow in hot places like Mexico and have long pointy leaves. Farmers cut off the pointy part of the leaves and juice them. Then, they cook the juice until it becomes thick and syrupy like honey.
Agave nectar is used to make things taste sweet, like desserts or drinks. It is a popular sweetener because it is natural and is said to be healthier than other sweeteners like sugar.
So, next time you eat something that tastes sweet, it might have agave nectar in it!
