Interactions
Bitter orange is a citrus fruit with several household and industrial uses, ranging from food additives to perfumery. It’s primarily used to make marmalades and jellies due to its high pectin content. Bitter orange is quite tart and unlikely to be eaten raw. Naturally high in pectin, a gelling agent, the fruit’s primary culinary application is for making marmalade. Bitter orange oil is also used as a flavoring or additive for preservatives (jellies), candy (chewing gum, hard candy, and candied fruit), desserts (ice cream, pies), sauces and chutneys, salad dressing, fermented wine. The juice of the bitter orange can be used as a marinade to flavor fish and meat. In some regions, it’s used similarly to vinegar. The extracted oils give a distinctive flavor to liqueurs like Grand Marnier. In China, bitter orange is used to make herbal teas and medicines. Bitter orange has several other household uses outside of the kitchen including soap substitues, essential oils (including neroli and petitgrain), perfumery, traditional medicine (such as antiseptics and hemostatics).
