Cheese Curds: Understanding The Magic Behind This Snack

Cheese curds are small, moist pieces of curdled milk, often made from cheddar cheese. They are eaten as a snack, deep-fried, or used in dishes like poutine. Cheese curds are made from fresh pasteurized milk to which cheese culture and rennet are added. After the milk curdles, it is cut into cubes, cooked, and pressed to release the whey from the curd, resulting in a mild flavour and rubbery texture. Fresh cheese curds are known for their squeak – a sound caused by the rubbing of milk protein strands against the enamel of the teeth.

What is a cheese curd?

Cheese curds are small, moist pieces of curdled milk, often made from cheddar cheese. They are eaten as a snack, deep-fried, or used in other dishes, most famously poutine. They are particularly popular in Quebec, Wisconsin, and Minnesota.

Cheese curds are made from fresh pasteurized milk to which cheese culture and rennet are added. Once the milk curdles, it is cut into cubes, resulting in a mixture of whey and curd. This mixture is then cooked and pressed to release the whey from the curd, creating the final product.

Cheese curds have a mild, slightly salty, cheddar-like flavour. Their texture is described as springy or rubbery, and they are known for the "squeak" they make against your teeth when bitten into. This sound is caused by the long strands of milk protein rubbing against the enamel of your teeth.

Cheese curds can be eaten alone as a snack, dressed with additional flavours such as herbs, garlic, or spices, or served with another food such as a small sausage or piece of cured pork. They are also commonly deep-fried and served with a dipping sauce.

How are cheese curds made?

Cheese curds are essentially fresh, mild-flavoured, springy or rubbery pieces of cheddar cheese. They are best enjoyed fresh and are often consumed as a snack, finger food, or appetiser. The process of making cheese curds is quite intricate and involves several steps.

Firstly, the milk is prepared by pasteurising it and heating it to 90°F or 96°F in a cheese-making vat. Cheese culture is then added to the milk, which transforms the lactose sugars into lactic acid, marking the start of the cheese-making process. Next, rennet, a coagulating agent, is introduced to the mixture, causing the milk to coagulate and separate into curds and whey.

After coagulation, the curds are cut into small cubes using special curd knives. This is followed by the cooking process, where the temperature in the vat is slowly raised from 90°F to 102°F, allowing the curds to continue releasing whey and firming up. Once the curds are cooked, they are drained and pressed to remove any remaining whey.

The final step involves cutting the large mass of curds into smaller slabs, which are then turned and stacked at regular intervals to expel more whey. This "cheddaring" process gives the cheese its distinct dense texture. Finally, the slabs are fed through a curd mill, which cuts them into finger-sized pieces, and the curds are salted and packaged for sale or immediate consumption.

It is important to note that the process of making cheese curds requires careful monitoring of temperatures and timings to ensure the desired outcome. Additionally, the ingredients used are relatively simple, with high-quality milk, salt, microbial rennet, and cheese cultures being the most essential components.

What do cheese curds taste like?

Cheese curds are mild in flavour, like fresh milk with a little salt. They are often described as a much milder, saltier version of cheddar cheese, akin to "a Brie without the funk".

They are typically eaten fresh, deep-fried, or breaded, and are best enjoyed straight out of the cheesemaker's vat, warm, and within two or three days of being made. The "'squeak' of fresh cheese curds against the teeth when bitten into is considered their defining characteristic. This "squeakiness" can be preserved by keeping the curds at room temperature.

Deep-fried cheese curds are often served with a side of ketchup, marinara sauce, or ranch dressing. They can also be dipped in batter before frying, like a mozzarella stick. Flavoured cheese curds are also available, including dill and buffalo sauce.

Cheese curds are a main ingredient in poutine, a Canadian dish that originated in Quebec in the 1950s. Poutine consists of French fries topped with cheese curds and gravy.

What is the squeakiness of cheese curds?

Cheese curds are fresh, mild-flavoured pieces of cheese with a springy or rubbery texture. They are often made from cheddar cheese, but can also be made from other types of cheese. They are usually yellow or orange in colour, although some varieties are white.

Cheese curds are known for their distinctive "squeak" when bitten into, which has been described by The New York Times as sounding like "balloons trying to neck". This squeakiness is caused by the rebound of the cheese's network of proteins, called casein, which are held together by calcium phosphate bonds. When a curd is bitten into, this network rebounds off the teeth, creating vibrations that result in the signature squeak.

The squeakiness of cheese curds is also affected by their freshness. After about 12 hours, even when refrigerated, cheese curds will lose much of their "fresh" characteristics, including the "squeak". This is due to moisture entering the curd. Room temperature, rather than refrigeration, may help to preserve the squeakiness. Additionally, the amount of enamel on the teeth can impact the squeak, with better enamel resulting in a louder squeak.

The "squeak" of cheese curds is considered by some to be their defining characteristic, and it is certainly a unique feature that adds to their appeal as a snack.

How are cheese curds served?

Cheese curds are often eaten as a snack, finger food, or an appetizer. They can be served alone, dressed with an additional flavor, or with another food, such as a small smoked sausage or piece of cured pork, with the elements skewered together on a toothpick.

For example, fresh curds can be dressed with jalapeño chilli peppers, garlic, various herbs, or spice blends such as Cajun seasoning, with garlic and dill on cheddar curds being a popular combination. They can also be battered and deep-fried, which is a popular way to serve them in Wisconsin, Minnesota, and at carnivals and fairs. Wisconsin-style deep-fried cheese curds are breaded, whereas Minnesota-style uses batter. They are sometimes served with a side of ketchup, marinara sauce, or ranch dressing.

In some areas, deep-fried cheese curds are also known as cheeseballs. In Wisconsin, they are usually referred to as fried curds.

Cheese curds are also a main ingredient in poutine, a dish that originated in Quebec, Canada, in the 1950s. Poutine consists of french fries topped with cheese curds and gravy.
