Sour cherries (Prunus cerasus), also known as tart cherries or acid cherries, are a small stone fruit belonging to the Rosaceae family, native to regions between the Black and Caspian Seas. They are distinct from sweet cherries (Prunus avium) due to their higher acidity, lower sugar content, and smaller size, typically measuring 1–1.5 cm in diameter. The skin color ranges from light red to deep burgundy, depending on variety, and the flesh remains translucent and juicy when ripe. Sour cherries have a characteristic tart-sweet flavor profile with a pronounced acidic bite balanced by subtle sweetness, making them less suitable for fresh eating than sweet cherries but highly prized for cooking, preserving, and baking applications.

Common varieties include Montmorency (the most commercially important), Balaton, Amarelle, and Morello, each with slight variations in acidity, color depth, and flavor nuances. When ripe, the fruit reaches peak tartness and flavor concentration, typically in late June through July in the Northern Hemisphere.

Sour cherries are fundamental to European and Middle Eastern cuisines, particularly in preserves, compotes, and traditional desserts. They are extensively used in pastries, such as Polish paczki, German cherry cake, and Austro-Hungarian strudel, where their acidity provides balance to sweet pastry doughs. In professional kitchens, sour cherry juice and puree feature in sauces for duck, game, and lamb, complementing rich meats with their bright acidity. They are staples in jam-making, liqueur production (notably Cherry Heering and Maraschino), and as a garnish for cocktails. Fresh sour cherries have a short harvest window and are often preserved through canning, freezing, or drying to extend their availability year-round. Their tartness makes them ideal for creating equilibrium in desserts that might otherwise be cloying, and they pair exceptionally well with chocolate, almonds, and vanilla.
