About National Cheese Curd Day
Cheese is made when milk is pasteurized and cooked until the whey separates from the curd. Then the curd is put into a mould and pressed to create a wheel or block of cheese. Any curds that aren't put into the mould are "cheese curds."
Sometimes called squeaky cheese, they are a regional delicacy in Quebec, Canada and some regions in the US.
What are Curds?
Essentially, curds are unaged cheddar cheese. They are separated from the whey early in the cheesemaking process and instead of being pressed into a block or wheel-shaped form, they are cut into randomly shaped sweet, salty morsels.
Why do they squeak?
The elastic protein strands in the curds rub against the enamel of your teeth to create that characteristic sound. The “squeak” is also a sign of curd freshness, which are traditionally eaten at room temperature, the same day they are made.
