When milk goes sour, it can be repurposed to make buttermilk or cheese. To do this, first, let the sour milk curdle. Then, use straining or filtration to separate the curds (solid) from the whey (liquid). Straining involves pouring the curdled milk through a fine mesh or cheesecloth to collect the solid curds while letting the liquid whey pass through. This method helps in utilizing sour milk effectively, turning it into valuable dairy products.
