The second marination in Chicken Tikka Masala tenderizes the chicken further and allows the flavors to penetrate more deeply, resulting in a more flavorful and succulent dish.
The process of marinating chicken twice in Chicken Tikka Masala serves a dual purpose. The first marination, typically involving ginger, garlic, lemon juice, and salt, primarily tenderizes the chicken. The acidity of the lemon juice helps to break down the protein structure of the chicken, making it more tender. This initial marination also begins to infuse the chicken with flavor.
The second marination, which usually includes yogurt, spices like garam masala, turmeric, cumin, and chili powder, builds upon the tenderizing effect and significantly enhances the flavor profile. The yogurt further tenderizes the chicken and helps the spices adhere better. The longer marination time allows the flavors to penetrate deeply into the chicken, resulting in a richer, more complex taste. This two-step process ensures that the chicken is both incredibly tender and intensely flavorful.
Don't over-marinate the chicken, especially in the second marination with yogurt. Over-marinating can make the chicken mushy due to the acidic nature of the yogurt. Aim for at least 2 hours, but no more than 8 hours for the best texture.
