Mango is native to India and is a drupe fruit, like a peach. The original mango trees can reach 35–40 meters in height. There are over 100 different types of mangos and they all have a leathery inedible skin. Mangos can be round, long, or oval. When ripe, the unpeeled fruit gives off a distinctive sweet smell. Ripe mangos are yellow, orange, red or green, depending on the variety. The most popular mango types are Kent and Keitt. Great substitutes for these types are Palmer and Haden. The flesh is yellow to orange and has a highly sweet flavour. In its center is an inedible seed.
