The avocado is a fleshy exotic fruit obtained from the tropical tree of the same name. In some parts of South America it is known as Palta. It measures 5-6 cm in length. The normal weight ranges between 200-400 g, although there are some units that weigh up to 2 kg. The skin is thick and tough, of a green colour; the tone depends on the variety. The oily pulp of cream to greenish-yellow colour has a very similar taste to nuts. It has a single round seed of pale brown colour, 2-4 cm long.
