The almond is a species of tree native to the Middle East and South Asia. Almond is also the name of the edible and widely cultivated seed of this tree. The fruit of the almond is not a true nut, but a drupe, consisting of an outer hull and a hard shell with the seed ("nut") inside. Shelling almonds refers to removing the shell to reveal the seed. Almonds are commonly sold shelled (i.e., after the shells are removed), or unshelled (i.e., with the shells still attached).
