The Greek yogurt experiment had mixed results. Let's examine them item by item...
Coagulation did not happen as scheduled. The recipe video indicated that one should expect nothing to appear to happen for the first 3 to 3½ hours and then a miracle would occur and there would be yogurt. Scientifically, this makes a lot of sense. The yogurt happens when the bacteria you are incubating reaches a certain concentration.
- First "uh-oh": my "miracle" didn't happen until 5½ hours had passed.
Greek yogurt is supposed to be very smooth and thick. The thickness comes from straining out the whey so I wasn't too worried initially that I had a lot of goop floating in a yellowish soup.
- Second "uh-oh": My curd seemed kind of grainy, more like ricotta cheese than the lump of soap I was promised in the video.
You are supposed to strain the yogurt for
several hours.
- Third "uh-oh": Mine was done giving up the whey in only a couple of hours. Can this be good?!
The yogurt was supposed to be smooth, silky, and delicious.
- Fourth "uh-oh": My yogurt was grainy and didn't taste like the yogurt I used for a starter.
At this point, I was very disappointed. I'd spent and entire day popping up out of my chair to check on the primordial soup in my crock pot and all I had to show for it was a couple of cups of not very tasty lumpy paste.
I nearly tossed it out in Thursday night's trash but then I had a minor epiphany: what if I jammed the stick blender into the yogurt and held the trigger until it cried uncle?
And so, that is what I did.
Friday evening, I processed the daylights out of the yogurt. Seriously, I buzzed the blender until my ears rang like I'd
closed down the bar after a heavy metal concert.
And the results were good! The final product is thick and smooth and creamy. The taste also improved over the intervening two days. Neatnik liked it. I enjoyed it with a spoon of honey. Number Guy, who does not like yogurt, even tried some with honey
on toast and liked it.
I'm glad I gave this a try, but at this point, I think that it was way too much work for too meager a return. I was chained to the house for the entire afternoon. I did manage to grade some papers and do a little bit of class prep between culture checks but, dudes... this was a major time suck.
Now I know how the commercial concerns can get away with charging twice the price for the Greek yogurt: it's worth the money not to have to babysit the bacteria. Besides that, they have all of the cool stainless steel vats and heating and cooling mechanisms and don't have to worry that the temperature in the crock pot is going to skyrocket during a two-minute bathroom break.
