The almond is the seed inside the fruit of the almond tree. Almond trees grow up to 10 metres tall. They are related to plums, cherries and apricots. Most people think of almonds as a nut, not the seed of a fruit.
Almonds can be eaten raw or roasted and salted, or used in cooking cakes and puddings.
