Zoranj su, or sour oranges, are a key ingredient in Haiti's cuisine. Also known as bitter oranges in English, they bring a unique tangy flavor to dishes. Their high acidity makes them an excellent partner in prepping, marinating, and cooking meats and seafood. With their robust and zesty taste, sour oranges add a distinct sharpness that elevates the overall flavor profile of a dish. The acidity of these oranges not only enhances the taste but also helps to tenderize the meat, resulting in juicier and more flavorful preparations.
