Curds are a dairy product obtained by curdling(coagulating) milk with rennet or an edible acidic substance such as lemon juice or vinegar, and then draining off the liquid portion. The increased acidity causes the milk proteins (casein) to tangle into solid masses, or curds.
In the Indian subcontinent etc., the Word "curd" is widely used to refer to what is known as "yogurt".
