Orange blossom water (also called orange flower water) is a clear, fragrant liquid distilled from the blossoms of the bitter orange tree (Citrus aurantium). It has a delicate, sweet citrus-floral aroma and is a staple flavoring in Middle Eastern, North African, and Mediterranean cuisines. Common applications include flavoring baklava syrup, scenting rice puddings, adding fragrance to beverages, and perfuming various pastries and confections.
In Dubai chocolate making, orange blossom water can be added to the pistachio cream filling or used to flavor the knafeh sugar syrup for an aromatic twist on the classic recipe. It pairs exceptionally well with white chocolate and pistachio, creating a light, floral-nutty combination. Like rose water, orange blossom water should be used judiciously — start with 1/4 teaspoon per batch. It is widely available at Middle Eastern grocery stores, specialty food shops, and online. Cortas and Nielsen-Massey are well-regarded brands.
