Description
Seeds can be eaten both raw and cooked, and they are often used in candies and pastries due to their mild and pleasant flavor. They can be eaten in large quantities as a dessert because the shell is thin and easy to crack. These seeds are considered superior in taste compared to C. ailanthifolia. Edible oil can be extracted from the seeds, although it tends to go rancid quickly. Young buds and stems of this plant can also be cooked and eaten.
