The Seville orange is a renowned citrus variety originating from Spain, particularly cherished for its distinctive bitter taste and smooth, bright orange skin. Unlike sweet oranges, the Seville is prized for its sharp, tangy flavour, making it the go-to choice for traditional marmalade. Its thick, aromatic peel is rich in essential oils, adding a fragrant zest to a variety of culinary creations. Beyond marmalade, the juice and zest of Seville oranges are often used to add a tart, citrusy kick to sauces, marinades, and baked goods.
