seville orange juice

Seville orange juice is the freshly expressed or processed liquid extracted from the Seville orange (Citrus × aurantium, also called bitter orange or sour orange), a hybrid citrus fruit native to Southeast Asia but historically associated with Seville, Spain. The juice is characteristically tart and acidic, with a complex flavor profile that combines bitter, sour, and floral notes—distinct from the sweetness of conventional sweet orange juice. Unlike eating oranges, Seville oranges are rarely consumed fresh due to their pronounced acidity and bitterness; their juice is prized in culinary and pharmaceutical applications for its aromatic complexity and preservative qualities. The juice typically has a pale yellow to golden hue and a pH below 3.0, making it highly acidic.

Seville orange juice is primarily used in marmalade production, where its natural pectin content and acidity facilitate gel formation, particularly in the British culinary tradition. In cocktails and beverages, it provides tart, bitter-forward citrus notes as a key ingredient in drinks such as the Sazerac and various tiki cocktails. The juice is employed in marinades and glazes for meat, poultry, and seafood, where its acidity tenderizes protein and its complex flavor enhances savory dishes. In Spanish and Mediterranean cuisine, it appears in sauces, dressings, and as a souring agent in dishes like ceviche or braised preparations. Small quantities are used in pastry work, cordials, and liqueurs for both flavor and preservation.
