Random Recipe #100 - Homemade Yogurt
This is a quick and easy way to make yogurt at home. You can get fancy, buy crazy equipment, research forever, but you are going to end up with the same stuff in the end. Here is why : you need 2 ingredients, a heat source and a good food thermometer.
Ingredients:
Milk
Starter Culture
Use what ever kind of milk you like. Of course it must be animal milk. Rice or Soy will not work. Starter cultures are available from specialty stores in a single or multiple strain batches, but the easiest way is get our friendly little microbes is to buy some plain, this means nothing added, yogurt from the grocery store. Look on the package and read the ingredients list, looking for active cultures. It is best to find one that lists only milk and cultures. Some add pectin, sugar, flavors, corn syrup, aspartame, or other stuff to adulterate the fine product that mother nature makes for us. These unwanted guests will also alter your homemade goodness. If you need to alter it do so one serving at a time after it is fermented.
I know, get to the point.... Here is how it is done in seven easy steps.
- Clean. Make sure everything is clean, it is best to sanitize all pots, vessels, utensils and thermometer, although not necessary.
- Heat. Heat your milk to 185 degrees F.
- Cool. Cool down to 100 degrees F.
- Pitch. Add your starter culture
- Incubate. Keep the cultured milk at or close to 100 degrees for about 7-10 hours.
- Package. Put away you homemade yogurt in clean or sanitized containers to be refrigerated.
- Eat. Enjoy with your favorite fruit or homemade granola.
Seems simple, it is. Our little buddies Lactobacillus do all the work for us. It really is easy, even though the commercial purveyors want us to think otherwise.

Clean
As mentioned it is best to sanitize all utensils and vessels, anything that is going to touch the milk starter culture or yogurt until you are ready to enjoy it. Why? Unwanted organisms, yeasts, molds, and other bacteria could contaminate the batch. Again, it is not a requirement and 99% of the time there we be no issues, especially if you keep your stuff and your paws clean. If you want to go the extra mile, and we do when we are fermenting at home, this is how. Find a good sanitizer, dip or spray all your stuff then rinse the sanitizer off with hot water that has been sterilized by boiling. Keep a couple of pots on the stove that have been boiled and while the water is hot after bringing to a boil rinse the sanitizer off. Clean is good, sterile is better. Star San is our favorite sanitizer, and it's easy to use; chlorine (bleach) and water will also work.
Heat
The trick here is to get the milk to 185 degrees F without burning or scorching. Why? We have to prepare the meal for our microbial companions by getting the milk sugar, lactose, and the proteins ready for consumption. How? Double boilers work great, or the good ole' microwave will also do the trick. Whether in the microwave or on the stove, low and slow is the way to go. We use a glass bowl and power level 3 or 4 in the microwave. The amount of milk you use will be the amount of yogurt you make (sans a small amount due to evaporation).
Cool
Submerge your vessel in cold water in the sink- be sure not to contaminate your product with your cooling water. Remember, not too cool- happy microbes live at 100 degrees. Why? Above 110 degrees, the starter culture will die of heat exhaustion.
Pitch
"Pitch" is the scientific term for adding a culture- please use as needed to impress your friends. Remember to make sure your product is below 110 degrees (this is important if you have not figured it out yet). You need to add approximately 1 tsp of starter (yogurt) to 1 quart of milk.
Incubate
This is where you get to be creative. Some people use heating pads, others fancy yogurt machines, us- a crock pot (a large one that cost a whopping $10 at our friendly neighborhood BigLots). The trick here is to keep things around 100 degrees. If using the crockpot, turn the power on & off of "low," ensuring that you keep things below 110 and above 90. If your crockpot is big enough, you can turn it into a water bath (heating the water around smaller vessels in the crockpot). You can even use the stove top- double boiler style. Incubation time is not critical, but needs to be at least 7 hours and 12 is probably more than enough.
Package
Use clean or sanitized (we do normally sanitize) plastic or glass containers to store. Close tightly and refrigerate.
Eat
This is our favorite step. You can add whatever you want. We often add homemade granola, a recipe to be explored in the near future, but fruit is also a good choice. Agave nectar or honey are the best options for sweetening if you must.
