扁桃

扁桃是蔷薇科李屬的一个种，原产于波斯，唐朝的《酉阳杂俎》和《岭表录异》对“偏桃木”有所记载。 其果核内的种子是常见的零嘴，香港、臺灣、星馬等中國大陸以外的中文地區所一般稱的「杏仁」其實是扁桃仁。 扁桃分為甜味扁桃(英文:Sweet Almond)和苦味扁桃(英文:Bitter Almond)兩種，其中甜扁桃可以食用，也就是一般食用的扁桃，苦扁桃則毒性過高無法食用。

Along with the peach, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the woody shell (endocarp) surrounding the seed. The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. Shelling almonds refers to removing the shell to reveal the seed.

Almonds are sold shelled or unshelled. Blanched almonds are unshelled almonds that have been treated with hot water to soften the outer skin, which is then removed to reveal the white embryo. Once almonds are cleaned and processed, they can be stored for around a year if kept refrigerated; at higher temperatures they will become rancid more quickly.

Almonds are used in many cuisines, often featuring prominently in desserts, such as marzipan. The almond tree prospers in a moderate Mediterranean climate with cool winter weather. It is rarely found wild in its original setting.

Almonds were one of the earliest domesticated fruit trees, due to the ability to produce quality offspring entirely from seed, without using suckers and cuttings. Evidence of domesticated almonds in the Early Bronze Age has been found in the archeological sites of the Middle East, and subsequently across the Mediterranean region and similar arid climates with cool winters. California produces about 80% of the world's almond supply.

Due to high acreage and water demand for almond cultivation, and need for pesticides, California almond production may be unsustainable, especially during the persistent drought and heat from climate change in the 21st century. Droughts in California have caused some producers to leave the industry, leading to lower supply and increased prices.
