Luxardo cherries are a type of maraschino cherry that are made using a traditional Italian recipe. They are known for their distinctive flavor, which is a result of the cherries being soaked in a syrup made from a blend of sugar and cherry juice. The cherries are also soaked in a solution of water, alcohol, and a small amount of food coloring to give them their bright red color.
One reason why Luxardo cherries are so tasty is that they are made using whole cherries, rather than being made from a puree or concentrate. This gives them a more natural, fruitier flavor than many other maraschino cherries. The syrup and alcohol used to preserve the cherries also contribute to their flavor, giving them a slightly sweet and slightly boozy taste.
Overall, Luxardo cherries are highly prized for their unique flavor and texture, which makes them a popular choice for use in cocktails and other recipes.
