Mangoes in their raw form are firm and unripe, with a green skin and a slightly sour taste. They are often used in cooking and pickling, as well as in salads and chutneys. Raw mangoes are a good source of vitamin C and fiber, and are known for their tangy flavor that adds a refreshing twist to dishes. When ripe, mangoes turn a vibrant yellow or orange color and become sweet and juicy, making them a popular fruit for snacking and desserts.
