Pepino melon - also known as tree melon, bush melon or mellowfruit.
It is a native to Peru, but now also grows in California and New Zealand.
The fruit is teardrop in shape and marked with yellow, brown or purple stripes.
They have a taste that is a mixture of cantaloupe and honeydew melon, but are the size of a plum.
When ripe the fruit is a dark yellow in colour and the stripes should be brown or purple.
They should be peeled before eating and then can be eaten on their own or in a fruit platter or go very well with a spinach salad.
