Cheese Spray: Salt Brine Preservation Techniques And Duration

The amount of time cheese stays in a salt brine depends on several factors, including the size and shape of the cheese, the desired salt content, the type of cheese, and the temperature of the brine. A general rule of thumb is to brine for one hour per pound of cheese and per inch of thickness. For example, a 2-pound block of Feta cheese would typically be brined for 2-3 days, while a 2-pound wheel of Gouda would be brined for 8-12 hours. Harder cheeses like Parmesan may require longer brining times, up to several weeks, while softer cheeses like Halloumi may only need 30 minutes to an hour.

How long does cheese stay in a salt brine?

The amount of time cheese stays in brine depends on several factors, including the size, shape, and type of cheese, as well as the desired salt content and brine temperature.

A general rule of thumb is to brine the cheese for one hour per pound of cheese per inch of thickness. However, this can vary depending on the specific cheese. For example, a dense, low-moisture cheese like Parmesan will require more time than a moist, open-textured cheese. Similarly, hard cheeses generally brine longer than soft cheeses due to their lower moisture content.

• Feta: 2-3 days for a 2-pound block
• Gouda: 8-12 hours for a 2-pound wheel
• Parmesan: Up to 3 weeks for large wheels
• Halloumi: 30 minutes to 1 hour

It's important to monitor the cheese closely during the brining process to achieve the desired taste and texture. The longer the cheese brines, the saltier it becomes. Additionally, flipping the cheese regularly during brining ensures even salt distribution.

What is a salt brine?

A salt brine is a solution of salt and water. The salt is typically sodium chloride or calcium chloride, and the water can be at room temperature or warmed to help the salt dissolve. Brines can be used for a variety of purposes, including food processing, cooking, de-icing, and industrial processes.

In the context of food, brines are used to preserve or season food. They can be applied to vegetables, cheeses, fruits, and some fish in a process known as pickling. Meat and fish are typically steeped in brine for shorter periods of time to enhance tenderness, flavour, and shelf life.

The process of brining involves soaking the food item in the brine solution, allowing the salt to penetrate and season the food from the inside out. This helps to retain moisture during cooking, resulting in a juicier texture. Additionally, the salt dissolves some of the meat's muscle fibres, making it more tender.

When creating a brine, the ratio of salt to water is important. Brines are typically described as a percentage, with most ranging from 5% to 10%. The type of salt used is also a consideration, as different types of salt have varying crystal sizes and densities. It is generally recommended to weigh the salt rather than measuring by volume.

For cheese specifically, brining is done to slow down or stop the bacterial process of converting lactose to lactic acid, as well as for added flavour. Brining also pulls moisture from the cheese's surface, aiding in the development of a rind and inhibiting the growth of moulds. The time required for brining cheese depends on the density and shape of the cheese, with denser and lower moisture cheeses needing more time in the brine.

Why is cheese salted?

Salting is an important step in the cheese-making process. Salt is added to cheese for several reasons, including:

Regulating Microbial Growth

Salt acts as an antimicrobial agent, inhibiting the growth of certain microbes. This can also allow more salt-tolerant microbes to grow.

Encouraging Moisture Loss

Salt draws whey (moisture) out of the cheese, drying it out and affecting its texture and stability. This process is important for rind development.

Altering Texture

Salt can directly affect the texture of cheese by altering protein structure or indirectly by removing moisture. The presence of salt can also change how microbes and enzymes behave, which has a significant effect on texture and flavour.

Enhancing Flavour

Salt not only gives cheese a salty taste but can also enhance other flavours or cover up unpleasant ones.

The primary reason for salting cheese is to slow down or stop the bacterial process of converting lactose to lactic acid. During the brining process, most of the lactose is removed. If the cheese were not salted, the residual moisture within the cheese would produce more acid than is ideal for proper ripening.

Additionally, salting cheese can help pull moisture from the surface, aiding in the proper drying of the cheese for rind development. It also inhibits the growth of mould.

How to make a brine solution

The process of brining involves submerging a cut of meat or cheese in a brine solution, which is essentially salt dissolved in water. Brining is a great way to add flavour and moisture to your food. Here is a step-by-step guide on how to make a brine solution:

Step 1: Gather Your Ingredients and Equipment

You will need salt, water, a non-reactive pan or container, and a stirring utensil. You can also add other ingredients such as sugar, herbs, spices, or calcium chloride to enhance the flavour of your brine.

Step 2: Prepare the Brine Solution

Start by warming your water to about 25°C (77°F). This temperature will help the water absorb the salt more effectively. The amount of salt you use will depend on the type of salt and the desired salinity of your brine. For a basic brine solution, use a ratio of 4 tablespoons of kosher salt per quart of water. If you are using fine table salt, reduce the amount to 3 tablespoons. You can adjust the salinity to your taste by adding more or less salt. Stir the salt into the water until it is completely dissolved.

Step 3: Add Optional Ingredients

If you want to add extra flavour to your brine, you can include ingredients such as sugar, herbs, spices, or calcium chloride to infuse your food with flavour during the brining process. For example, you can add lemon rind and rosemary for a citrusy, aromatic brine, or brown sugar and molasses for a deeper, sweeter brine.

Step 4: Cool the Brine

Once your brine is prepared, allow it to cool to room temperature or the desired temperature for brining. It is best if the brine and the food you are brining are at similar temperatures. For cheese, a temperature of 13°C (55°F) is recommended, while meats are typically brined at refrigerator temperatures.

Step 5: Submerge Your Food

Place your cheese or meat into the brine solution, ensuring that it is fully submerged. If your food is floating, you can use a weight to keep it below the surface. Cover the container and let it sit in the refrigerator for the recommended time based on the type of food and the desired level of brining.

Step 6: Remove and Prepare Your Food

After brining, remove your cheese or meat from the brine, pat it dry, and proceed with your recipe. Remember to take into account the additional salt that your food has absorbed during brining when seasoning your final dish.

How to brine your cheese

Brining is an essential step in the cheese-making process. It helps to preserve the cheese, control moisture, and develop flavour and texture. Here is a step-by-step guide on how to brine your cheese:

Step 1: Prepare the Brine Solution

The first step is to prepare a brine solution with the right concentration of salt. The ideal salt concentration can vary depending on the type of cheese you are making. For soft cheeses, a lighter brine (around 6-8% salt concentration) is recommended, while for hard cheeses, a higher concentration (18-25%) may be used. To make the brine solution, dissolve the desired amount of salt in water. It is important to use non-iodised salt, as iodised salt can affect the flavour and colour of the cheese. You can also add calcium chloride to the solution to improve the texture of the cheese.

Step 2: Cool the Brine Solution

Once the salt is dissolved, let the brine solution cool to room temperature (around 20-22°C). Using hot water can cause the salt to precipitate as the brine cools. You can speed up the cooling process by placing the container in a cool location or in the fridge.

Step 3: Check the Brine Concentration

To ensure that your brine is ready, perform a float test by placing a raw egg in the solution. If the egg floats, your brine is ready. If it sinks, add more salt until it floats. Alternatively, you can use a hydrometer to measure the specific gravity of the solution, which should be around 1.2 for a saturated brine.

Step 4: Prepare the Cheese

After your brine is ready, it's time to prepare your cheese for brining. Make sure that your cheese has been pressed and cooled to a temperature similar to that of the brine solution. Brining warm cheese can result in oversalting.

Step 5: Submerge the Cheese in the Brine

Fully submerge the cheese in the brine solution. Use a weight if necessary to keep the cheese submerged. The brining time will depend on the type of cheese and your desired salt content. For example, Feta cheese should be brined for 2-3 days, while Gouda only requires 8-12 hours. Regularly turn the cheese during brining to ensure even salt distribution.

Step 6: Remove the Cheese from the Brine

Once the brining process is complete, remove the cheese from the brine and pat it dry with a clean cloth or paper towel. Allow the cheese to air dry for 24-48 hours before ageing or packaging. This step helps form a protective rind on the cheese.

Step 7: Age the Cheese

Finally, store your brined cheese in a controlled environment with the right temperature and humidity for ageing. The ideal temperature and humidity levels can vary depending on the type of cheese, but generally, aim for a temperature of 50-55°F (10-13°C) and humidity of 80-85%. During ageing, regularly turn the cheese and wipe off any excess moisture or unwanted mould growth.
