Description

Seeds can be eaten both raw and cooked. They have a sweet and distinctive flavor that is perfect for desserts and are commonly used in pastries and cakes. It can be tricky to remove the core from the seed pod, and the oil extracted from it can go rancid quickly. Unripe fruits can be pickled. The seeds grow either solitarily or in pairs and have a diameter of 3-4 cm. Be careful, as the nuts can leave permanent stains on clothing. Edible oil is extracted from the seeds, which has a sweet taste but can spoil quickly. It is used as a flavoring in bread, pumpkin, and other foods. The juice from the structure can be drunk or concentrated into syrup or sugar. This juice can be tapped in the spring.
