Pecans are a type of nut that come from the Carya illinoinensis tree, native to the southern United States and northern Mexico. They have a rich, buttery flavor and are often used in desserts, such as pecan pie, as well as in savory dishes. Pecans are a good source of healthy fats, protein, and various vitamins and minerals, making them a nutritious snack option. These nuts are typically harvested in the fall and can be eaten raw or roasted. Pecans are also used to produce pecan oil, which is valued for its flavor and cooking properties. Additionally, they are a popular ingredient in trail mixes and granola bars.
