Whey is a byproduct of the coagulation of proteins and fats in milk and cream during the cheese-making process. It can be used to make ricotta cheese, which is a creamy, white, mild, and soft cheese. To make ricotta from whey, the whey is heated and strained through a cheesecloth, and then hung in a flour sack to separate the remaining whey from the curds. The curds are then salted and stored in an airtight container in the fridge. Aside from making ricotta, leftover whey has many other uses, such as making butter, pest control, and as a substitute for water in recipes like bread and pancakes.

Make ricotta cheese
Making ricotta cheese from whey is a simple and quick process. You can use whey from goat, cow, or sheep's milk. However, it is important to note that this method of making ricotta cheese will only work if the whey was produced from making cheese without acids like vinegar, lemon juice, or citric acid.
Firstly, heat the whey without agitating it. It is best to use fresh whey, and the temperature should reach 160°F. At this point, you can add fresh milk (5-12%) to improve the richness and yield of the ricotta cheese. Continue heating to 170°F, then add 1/2 teaspoon of salt for every gallon of whey and mix quickly.
Next, continue heating the mixture without agitation until it reaches 185°F. Some people choose to heat it to just below boiling (200°F), although this is not necessary. Once the desired temperature is reached, hold it there until the ricotta rises.
Now, mix 1/2 teaspoon of citric acid per gallon of liquid. Dissolve the citric acid in 1/2 cup of water before adding it to the pot. Stir briskly for 5-10 seconds, and you will see curds forming small flakes that gradually become larger curd masses. If needed, add a bit more citric acid solution.
As the curds rise, use a perforated ladle to gently move them from the sides to the center of the pot. These clumps of curd will begin to consolidate and float on top of the liquid. Let the curds rest for 10-15 minutes, as this is an important step in assuring the final quality of the ricotta cheese.
Finally, ladle the curds gently into draining forms. If you were patient in the previous steps, no cheesecloth should be needed. Let the curds drain for 15 minutes up to several hours, depending on the desired texture of your ricotta cheese. For a fresh and light ricotta, drain for a shorter time until the free whey drainage slows, and then chill to below 50°F. On the other hand, for a rich, dense, and buttery texture, allow the curds to drain for a longer period (several hours).
You can use a colander, strainer, or bowl lined with a cheesecloth to collect the whey. If you want to hang the cheesecloth, gather the ends, tie them, and hang the cloth on a kitchen cabinet with a bowl underneath to catch the remaining whey. Depending on the amount of whey, this can take one to several hours.
Once the whey has cooled down to 140°F or less, you can use a ladle to transfer it to a container. The ricotta cheese can be stored in an airtight container in the refrigerator and used within a week. It is recommended to let the cheese cure in the fridge for about 24 hours before serving to enhance its flavour.

Make mozzarella cheese
Making mozzarella cheese at home is an enjoyable process, and it can be done in several ways. Here is a simple guide on how to make mozzarella cheese, which will then allow you to use the leftover whey to make ricotta cheese.
First, you will need to prepare your ingredients and equipment. For mozzarella, you will need milk, citric acid, rennet, salt, a large pot, a long knife, a colander, a cheesecloth, a ladle, a large bowl, and a microwave-safe bowl. The milk should be at least three days old for mozzarella.
Begin by pouring the milk into the large pot and heating it to around 32 degrees Fahrenheit (or just below body temperature). Once the milk is at the correct temperature, add the citric acid and stir gently for about 30 seconds. Then, add the rennet and gently stir for another 30 seconds in a top-to-bottom direction. Leave the milk to sit for 5 to 15 minutes until it has set and formed a curd.
Next, you will need to cut the curd. Using your long knife, cut the curd into a grid pattern, with strips about an inch wide. Cut down to the bottom of the pot and then lift the knife to ensure the curds are separated. Leave the mixture to sit for about 10 minutes, and you will see the curds start to shrink and the whey (the liquid) begin to fill the pot.
Now, it is time to heat the mixture. Slowly heat the pot to 100 degrees Fahrenheit, stirring gently to prevent the curds from sticking to the bottom of the pot. Once the mixture reaches 100 degrees, stop stirring and maintain this temperature for about 40 minutes.
After this, remove the pot from the heat and leave it to sit for 5 minutes. Then, use your ladle to transfer the curds to the cheesecloth-lined colander, which should be placed over the large bowl to catch the whey. The whey can be reserved for making ricotta. Gently gather the corners of the cheesecloth and twist them together to form a ball. Squeeze gently to remove excess whey, then leave the curds to sit for a few minutes.
Finally, microwave the curds in a microwave-safe bowl for about a minute, until they are melted. Add salt to taste, then knead the cheese with your hands until it is stretchy and smooth. Your homemade mozzarella is now ready to be enjoyed!
Remember to use the leftover whey to make ricotta cheese by following the steps outlined in the previous response. Enjoy the process of crafting your own cheeses at home!

Make butter
Whey butter, while not technically a cheese, can be made by skimming the fat that floats to the top of the whey left after cheesemaking. This process requires you to let the whey cool for a few hours or overnight. The cream in the whey will rise to the top and can then be scooped away for butter-making. The fat collected can then be churned into a rich, flavorful butter. Whey butter has a distinct, slightly tangy flavor due to the residual lactic acid in the whey.

Pest control
Whey is an excellent natural pest control solution. It can be used to maintain your plants' health and keep them free from pests. If you have leftover whey from making ricotta cheese, you can use it to protect your plants from pests. Here's how:
Firstly, strain the whey to remove any solid particles. This step is important to ensure that the whey can be easily mixed with water and sprayed on plants without clogging the sprayer. After straining, dilute the whey with an equal amount of water. Mix the strained whey and water together to create your pest control solution.
Once you have prepared your diluted whey solution, it's time to apply it to your plants. Use a spray bottle or a watering can to apply the solution directly to the leaves and stems of your plants. Make sure you coat the plant surfaces thoroughly, paying extra attention to the undersides of leaves, where pests often hide.
The diluted whey solution is particularly effective against powdery mildew, a common fungal disease that affects many types of plants. By regularly spraying your plants with the whey mixture, you can help control and prevent the spread of this disease.
In addition to pest control, whey also has other benefits for your plants. When applied to the soil, it can help lower the soil's pH, making it more acidic. This is especially useful if you are growing plants that thrive in acidic conditions, such as tomatoes or hydrangeas.
Using whey as a natural pest control solution is a great way to reduce waste and utilize the byproduct of your cheese-making process. Not only will it help keep your plants healthy and pest-free, but it also provides additional benefits to the soil and the plants themselves.

Feed to animals
Whey from ricotta cheese can be fed to animals, but it is important to do so in moderation. Herbivorous and carnivorous animals can benefit from the protein and sugars in whey, but overconsumption can upset their regular diets. For example, chickens can be fed whey sparingly due to the protein content already being present in their feed. Additionally, pigs have been known to enjoy whey, especially when it is combined with vegetable scraps to make them more appealing. Dogs can also have whey as an occasional treat, and it can be used to soak their dry food, adding a probiotic boost. Cats may or may not choose to consume whey, as they can be fickle in their food choices.
It is important to note that some animals may have negative reactions to whey. In one instance, a farmer fed whey to grass-fed ruminants, and a few of the animals got sick, while others avoided it altogether. It was suspected that the active enzymes in the whey caused stomach bloating in these animals, but they all survived. Therefore, it is essential to introduce whey gradually and monitor the animals' reactions.
When feeding whey to animals, it is also crucial to maintain proper hygiene and storage practices. Whey should be refrigerated and consumed within a few days to prevent spoilage and the growth of harmful bacteria. Additionally, troughs or feeding bowls should be washed regularly to prevent the build-up of bacteria that could potentially harm the animals.
Overall, whey from ricotta cheese can be a nutritious treat for animals when fed in moderation and with proper hygiene practices in place. It is always a good idea to consult with a veterinarian or animal nutritionist to determine the appropriate amount of whey to feed, depending on the specific animal's dietary needs.
