Flavor: Cottage cheese has a milder flavor compared to the tangy profile of sour cream. This substitution will diminish the acidity and complexity typically imparted by sour cream, leading to a more neutral taste. If the cottage cheese is not blended or whipped, the slight tanginess it does provide may be unevenly distributed, potentially affecting the flavor consistency in the final product.
Texture: Replacing 1 cup of sour cream with cottage cheese will result in a denser texture due to the curds present in cottage cheese. This substitution may lead to a slightly less smooth crumb structure, as the curds do not dissolve completely during baking. The moisture level in cottage cheese is similar to sour cream, which helps maintain some moistness in the baked good; however, the mouthfeel might be grainier if the curds are not blended well before use.
