Yogurt tenderizes kebabs by breaking down proteins and adds moisture, resulting in a softer, more succulent texture.
Yogurt's magic in kebabs comes from a few key properties. First, it contains lactic acid, a mild acid that gently denatures the proteins in the meat. This process weakens the protein structure, making the meat fibers more tender and less likely to become tough during cooking. Think of it as a natural meat tenderizer.
Second, yogurt adds moisture. As the kebabs cook, the yogurt's moisture helps to keep the meat hydrated, preventing it from drying out and becoming chewy. The yogurt also helps the spices and other flavorings adhere to the meat, creating a delicious crust.
Finally, the fat content in yogurt contributes to the overall richness and mouthfeel of the kebabs. It helps to create a more luxurious and satisfying eating experience. The longer the meat marinates in yogurt, the more pronounced these effects will be.
Use plain, full-fat yogurt for the best results. Greek yogurt works well too, but you may need to thin it slightly with a little water or lemon juice to ensure even coating of the meat. Avoid sweetened or flavored yogurts, as they can negatively impact the flavor of the kebabs.
