Probiotics are expensive! Did you know you can grow your own? Yogurt is a great source. Fermenting vegetables is another.
Making your own yogurt is easy, and cost effective.
Your favorite milk, (I use organic whole milk), and yogurt with active cultures.
Put the milk in a pan, in this batch I made almost a gallon. It keeps a long time.
Heat the milk to 180 degrees, stirring to keep it from scalding. This kills off the bad bacteria.
Cool the milk to 110 degrees. 110 is the right temp for the healthy bacteria to grow (probiotics).
Add 1/4 cup of yogurt with active cultures per half gallon of milk. I have about a 1/2 cup here. Add some warm milk to the yogurt, and gently stir.
(After your first batch, just use some from the last batch.)
Add the mix to the rest of the milk.
Put the yogurt in glass containers, and then into a cooler, with a bottle of hot tap water.
Cover the whole thing with a blanket.
Leave for 12 hours undisturbed. This makes a very thick yogurt like Greek. If you want it thinner, start checking it at around 8 hours.
I like mine as is. You could add sweetener, and/or vanilla. Cinnamon is also good.
Let me know how it goes!
