Cheese curds are the fresh curds of cheese, often cheddar. Their flavor is mild with about the same firmness as cheese, but has a springy or rubbery texture. Fresh curds squeak against the teeth when bitten into, which some would say is their defining characteristic. The American variety are usually yellow or orange in color, like most American cheddar cheese. Other varieties, such as the Québécois and the New York varieties, are roughly the same color as white cheddar cheese.
After twelve hours, even under refrigeration, they have lost much of their "fresh" characteristics, particularly the "squeak". Room temperature, rather than refrigeration, may preserve the flavor and the "squeak".
You can freeze cheese curds for up to 4 months, be aware you will loose the squeak and freshness when eaten after freezing.
Cheese Curds are sometimes breaded and deep fried especially in Wisconsin.
Cheese curds are a main ingredient in Poutine, a Quebec dish in which cheese curds are served layered on top of french fries, and melting under steaming hot gravy.
