Yogurt is super easy to make from scratch and you do not need any fancy yogurt makers or thermometers to have delicious and creamy yogurt at home for cheap.
One large stock pot or water bath canner
Four clean or sanitized quart mason jars with lids and rings
Tongs to remove hot jars from pot
Insulated Cooler (the kind you take to a barbecue)
One gallon of homo (whole) milk
1 single serving package of plain yogurt containing live, active cultures or an amount of plain yogurt equal to about 8-12 tablespoons
Fill mason jars about 2 inches from the top with milk and place filled jars in the stock pot (or water bath canner) and fill pot with water and bring to a boil.
Allow to boil until milk in jars form a “skin” (you will notice possible wrinkles on the surface of the milk at this time)
Remove jars carefully from boiling water using tongs and allow to cool for about 30 minutes to 1 hour. Jars at this time should be warm to the touch but not hot.
Take the hot water you boiled and pour it into the cooler and cover with the cooler’s lid.
Stir in two to three tablespoons of plain yogurt. This is to inoculate your milk with good bacteria.
Put the lids and rings on the mason jars of inoculated milk and place jars in the cooler so they are in the hot water but not fully immersed. (I would say a few inches of water is perfect.) The water is to keep the temperature warm enough to encourage the bacteria to grow but not so hot to kill it off.
Leave the sealed jars in the hot water in the lidded cooler for about 8-12 hours. You will need to add more boiling water to the cooler a couple times over that period so it is best to do this during the day rather than at night when you might not remember to add more boiled water.
After about 8-12 hours open one of the jars. The milk should have thickened and turned into a yogurt consistency. Remember your yogurt may not be as thick as store bought brands as it does not contain gelatin and other additives.
Transfer your four jars of yogurt to the fridge and enjoy!
On a weird side note I find homemade yogurt lasts longer that the store bought kind. Make sure to look at and sniff your homemade yogurt to regularly check for signs of spoilage.
I hope you like this recipe!
