Yogurt-- I Finally Made It!

If you were following along with my household dramas in the Fall of 2009, you'll remember my yogurt making experiments- sans a yogurt maker appliance- went bust (see the post here). Three times I followed recipes that failed to produce anything but sour milk and a phlegm like texture.

Its been a year and a half and I finally felt ready to brave the experiment again (Thanks for the inspiration, Evelyn at A Chaotic Lifestyle). 

I'll skip the suspense to announce my final results, in a frenzy of caps lock excitement: THREE TIMES I'VE SUCCESSFULLY, MIRACULOUSLY turned milk to yogurt! 

While the first re-trial came out more like Yop than Yogurt, which I froze as popsicles and no one knew the difference, the second and third were progressively more firm. I've Mother Earth News to thank for the instructions. Find the full article at Mother Earth News. 

For the curious, I simplify the process below. If you decide to try it, reference the full article at MEN.

First, I melted 2 T of honey at bottom of pot to prevent milk scalding at the heat source.

Then on mid-low heat for about 30 minutes, I heated four and a half cups of milk until skin formed on top- with bubble trapped below. Turning off heat, I cooled milk for another 30 minutes until it didn't burn by inner wrist- but it stung (did mention there is some masochism involved in this?)

As the milk heated and cooled, I added a couple tablespoons of raspberry jam to the bottom of 2 of 3 clean, 500 ML jars. I kept one plain so I had starter for next time.

Once the milk was 115 F (hot but not too hot to the touch), I mixed in a couple Tablespoons of 'starter'. The yogurt contained NO gelatin, and ACTIVE bacteria cultures. I also added 3 Tablespoons of skim milk powder.

I then placed the jars in the crock pot and filled it with HOT water. I occasionally and shortly turned the crockpot on low to keep the water warm.  When I headed to bed, I placed the glass covered pot under the cabinet lights. This seemed to keep the water relatively warm. In the morning, I checked how thick the yogurt was (it wasn't quite ready) then kept the yogurt in a warm bath for most of the day. When the yogurt finally seemed thick enough, I refrigerated the jars.

[On another occasion, I put the jars in my dutch oven and placed this into a cooling oven. Along with the oven light on overnight, this provided enough heat to solidify the yogurt.)

The four and a half cups of milk produced the equivalent amount of yogurt: about a tub and a half of the standard 650 g worth about $5- 8 at the store. Homemade it cost me $1.25. After doing it three times, I feel pretty confident that I could do it regularly without much trouble-- most of the time it takes to make involves me sleeping, surfing the net, and working on other things in the kitchen. 

Tonight, I'm happily calculating how many pairs of shoes and Lee Valley garden tools I can buy with my savings. As I do, I'm sucking a raspberry, yogurt popsicle that once was Yop, which before that was milk in my fridge.
