Almond is the edible seed of Prunus dulcis, a species of tree native to Iran but widely cultivated elsewhere. It is classified with the peach in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell surrounding the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo.
