Overview
The apple is the pomaceous fruit of the apple tree, species Malus domestica in the rose family (Rosaceae). It is one of the most widely cultivated tree fruits globally. The flesh is crisp and juicy, ranging from tart to sweet depending on variety, with thin edible skin that may be red, green, yellow, or bicolored.
Origin and history
The apple tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found today. Apples have been cultivated for thousands of years, spreading along the Silk Road to Europe and later to the Americas with European colonists [1]. In the United States, commercial apple cultivation expanded rapidly in the 19th century, with the fruit becoming a staple of temperate-climate agriculture.
Varieties and aliases
- Malus domestica (the cultivated apple species; Malus pumila is a synonym)
- Andong-sagwa (Andong apple, a flagship Korean variety from North Gyeongsang province) [4]
- Crab apple (small, tart wild or ornamental varieties, Malus spp.)
- Cooking apple (any tart variety used primarily for baking or sauce)
- Eating apple (any sweet variety consumed raw)
Culinary uses
Apples are eaten raw, baked, stewed, juiced, fermented into cider and vinegar, and dried. They anchor desserts such as apple pie, apple crisp, and tarte Tatin. In savory cooking, apples appear in pork roasts, salads, and chutneys. In Persian cuisine, khoresh-e sib is a lamb stew with sour green apples, yellow split peas, cinnamon, and saffron [3]. In Korean cooking, apples are used as a sweetener and tenderizer in marinades for bulgogi and as a component of cho-gochujang dipping sauce [4]. In the Philippines, pineapple is far more common than apple in savory dishes, but apple appears in some urban fruit salads and halo-halo variations [2].
Cross-cuisine context
In Korean cuisine, the Asian pear (Pyrus pyrifolia) is more commonly used for the same tenderizing and sweetening functions that apples serve in Western cooking, though apples are now widely grown in Korea and used interchangeably in many dishes [4].
Notes for cooks
- For baking, use firm, tart varieties such as Granny Smith or Braeburn that hold their shape when cooked.
- Apples ripen from the outside of the tree inward; a ripe apple should be firm with no soft spots and should have a noticeable aroma at the stem end.
- Store apples in the refrigerator crisper drawer away from strong-smelling foods; ethylene gas from apples will accelerate ripening of nearby produce.
