The first step in cheese making is to gather the raw materials. The main ingredient in cheese is milk, but the type of milk used can vary. Some are made from cow’s milk, while others are made from or goat milk. Some cheeses are even made from a combination of different milks.
Once the milk has been collected, it is heated to a specific temperature to pasteurize it and kill any harmful bacteria. Then, a coagulant is to the milk to solidify it. This coagulant can be any number of things, including rennet (an enzyme found in animal stomachs) or vinegar.
After the coagulant is added, the mixture is left to sit and curdle for several hours. During this time, the curd separates from the whey. The whey is then drained off, leaving behind a solid mass of curd.
The next step is to add salt and the desired bacteria to the curd. The bacteria will continue to ferment the cheese, giving it its unique flavor and texture. Depending on the type of cheese, different bacteria are used. For example, cheddar cheese is commonly made with a bacterium called Lactobacillus lactis, while blue cheese is made with a bacterium called Penicillium roqueforti.
Once the bacteria have been added, the curd is shaped and pressed into molds. The molds help give the cheese its shape and texture. Some cheese makers add additional ingredients, such as herbs or spices, at this stage to give the cheese additional flavor.
Finally, the cheese is aged for several weeks or even months, depending on the type of cheese. During this time, the cheese is stored in a temperature-controlled environment and regularly turned and brushed to prevent mold growth. The aging process is crucial as it helps develop the cheese’s distinct flavor and texture.
In conclusion, cheese making is a complex process that requires a lot of skill and expertise. While the general steps are the same for most cheeses, each type of cheese has its unique nuances and requirements. So next time you enjoy a beautiful cheese plate, take a moment to appreciate the art and science that went into making your delicious treat.
