Ready for a great protein supplement? Let’s get started.

What You Will Need

Based on many hours and days of experimenting, I have brought my gear down to just a few things: 

  • Fresh milk
  • 2 lemons
  • Flavourings (vanilla essence or cocoa powder)
  • 2-gallon pot
  • Food thermometer
  • Cheesecloth
  • Mason jar

Step One: Pour the Milk

Pour milk into the pot. The amount of milk you use will determine how much whey you end up with. For example, if you use a gallon of milk, you should get around 120 grams of protein.

Pro Tip: You can use other dairy products like greek yogurt or cream cheese, but these are not nearly as effective as pure milk. Furthermore, never use almond milk.

Step Two: Heat the Milk

Place the pot on the stove and heat the milk until it reaches 190 degrees Fahrenheit. Use a food thermometer to check the temperature of the milk as it heats up.

Step Three: Lemon Juice

Once the milk reaches 190 degrees Fahrenheit, take it off the stove and add the lemon juice. Stir well until the lemon juice is fully mixed in [1].

Pro Tipwe suggest using a full lemon for every half gallon of milk used.

Step Four: Rest

Now it’s time for the milk and lemon mixture to rest. Cover the pot with a lid and let it sit for 30 minutes. This allows the mixture to separate into whey and curds. Right now, you have liquid whey.

Step Five: Strain

After 30 minutes, it’s time to strain the mixture to get liquid whey. Place a cheesecloth over a mason jar and slowly pour the mixture into the cheesecloth-covered jar. The whey will drip through the cheesecloth and into the mason jar while the curds stay behind.

Once all the whey has dripped through the cheesecloth, rinse the curds with cold water. This helps to remove any lingering whey and makes the curds taste better.

Step Six: Drain

Place the bowl and the cheesecloth in the fridge for 2-3 hours to allow the mixture to cool down. Putting it in the fridge will also help prevent the mixture from spreading.

Pro Tipto speed up the process, you can also place the mixture in the freezer for 1-2 hours.

Step Seven: Dehydrate the Whey

The best way to dehydrate whey is by using a dehydrator [2]. If you don’t have a dehydrator, you can use an oven set to the lowest temperature possible. Place the whey on a baking sheet and bake for 10-12 hours.

Pro Tip: You will get optimal nutrition from your whey protein supplement if you use a dehydrator instead of going through the oven process.

Step Eight: Blend

Once the whey powder is dry, place it in a blender and blend until it’s a fine powder. This is also when you can add any flavorings if you want to give your powder a little something extra.

While pure whey protein powder is fine on its own, flavored protein powder makes things a little more interesting and can also make you more eager to down that protein shakes.

Pro Tip: We quite like putting matcha green tea powder in ours. Vanilla powder or dried vanilla beans can also be delicious.

Step Nine: Store

Once the powdered whey is a fine powder, you can STORE it in an airtight container. It will last for up to 6 months.

Hi there, I’m Kate Young and I’m a fitness coach from California, but I now live in Austin. I have been involved in so many different sports over the years, including swimming, running, athletics, gymnastics, rugby (yeas, you read that right), baseball, tennis, and so many more that I have lost count.

I just love competing in sports, but struggled to find the one that I would stick with. So, instead I decided to become a fitness coach as it allows me to work with so many different types of athletes.

I’ve also become heavily involved it diet. The reason for this is that I’ve seen too many athletes fail in their fitness goals because their diet didn’t support it. And I’ve seen just as many people fail in their diets, because their fitness activities weren’t effective.

A lot of my work has involved working up with college tennis teams where I have tailored some endurance type fitness programs. Tennis coaches are great at teaching techniques, but a lot of them struggle with general fitness levels.

And that’s where I come in. On this site I contribute to anything tennis, fitness and diet related, which will help you get to your goals quicker and with more ease. And if you have some very specific questions then why not reach out on one of the social media channels where all of us are very active.

We will be happy to hear your thoughts
