Rose apple, also known as Syzygium jambos, is a tropical fruit native to Southeast Asia. It has a round or oval shape and a thin, green or yellow skin when ripe. The flesh of the fruit is crisp and has a sweet, floral flavor. It surrounds a single, small seed in the center. Rose apple is often eaten fresh or used to make desserts, such as ice cream and smoothies. It is also a good source of vitamins and minerals, including vitamin C, potassium, and iron. When ripe, the fruit will be firm to the touch and have a slightly sweet aroma. It can be stored at room temperature until it is ripe, and then refrigerated until it is ready to be eaten.
