Nuts are becoming increasingly popular as a crunchy and nutritious snack. Pecans are one of the most popular edible nuts. The pecan tree is a large deciduous tree belonging to the hickory family. A typical pecan has a buttery rich shell which is golden brown outside and beige inside. The kernel occupies 40% to 60% of the space inside the shell. This kernel has a grooved surface but is slightly more oval in shape. The pecan has a sweet, rich and buttery flavor and texture which can be attributed to its high levels of monounsaturated oils. Pecans have a fat content of over 70% which is the highest among all the nuts. Shelled pecans are available all year round while unshelled pecans are available in autumn.
