A green apple is a type of apple that is typically tart and crisp. The most common variety is the Granny Smith, known for its bright green skin and firm texture. Green apples are often used in cooking and baking, as their tartness can enhance flavors in dishes like pies and salads. These apples are rich in vitamins, particularly vitamin C, and provide dietary fiber. They can be enjoyed fresh, sliced, or juiced. Green apples are also popular in smoothies and can be paired with various cheeses for a tasty snack.
