Description

Seeds can be eaten raw or used in baked goods such as cakes and ice cream because of their delicious flavor. They can also be ground into flour and serve as a flavoring in both sweet and savory dishes. Unripe fruits are often pickled in vinegar. Edible oil can be extracted from the seeds, but it should not be stored for too long as it can quickly become rancid. The oil has a pleasant taste and is used in salads and for cooking. In spring, sap is harvested from the plant and used to make sugar. Finely ground shells are used in making pasta 'agnolotti' and also serve as a spice fixative. Dried green husk contains 2.5-5% ascorbic acid (vitamin C) and can be extracted and used as a vitamin supplement. Leaves of the plant are used to make tea.
