Verjuice is a unique ingredient that adds a tangy and acidic flavor to dishes. It is made from the juice of unripe grapes or other sour fruits. Verjuice has a similar acidity to vinegar or lemon juice but offers a milder and more complex taste. It is commonly used in cooking and is particularly popular in French and Middle Eastern cuisines. Verjuice can be used as a flavor enhancer in sauces, dressings, marinades, and vinaigrettes. It can also be used to deglaze pans, adding depth of flavor to dishes.
