Cooking apples are a type of apple specifically cultivated for culinary use rather than for eating raw. They are typically tart and firm, which allows them to hold their shape during cooking. Common varieties include Granny Smith, Bramley, and Cortland. These apples are often used in pies, sauces, and other baked dishes due to their ability to balance sweetness and acidity. When cooking with apples, it's important to choose the right variety for your recipe. Cooking apples generally require more sugar than sweet eating apples, as their tartness can dominate the flavor. They are also rich in pectin, which helps thicken sauces and preserves.
