For lush tropical juiciness and sweet flavours pawpaw and papaya, are up there with the best. Originating from Central and South America, these oval-shaped fruit can grow up to 30cm in length. Packed with all kinds of nutrients, including vitamins A and C, potassium and magnesium, they’re a perfect healthy snack.
Papayas have red-orange flesh and a yellow-orange skin and pawpaws have yellow flesh and a light orange skin. Papayas are the sweeter of the two. There are two main varieties of papaya grown in Australia and these are available all year round. Also available is green papaya, which is used mostly in Asian-style dishes.
Choose near-ripe fruit – they’re ripe if the skin is a yellowish orange colour. Also, check that the skin is smooth and unblemished and that the fruit feels heavy for its size.
Ripen at room temperature until the fruit gives slightly when pressed.
