Mad Scientist Makes Yogurt
« on: July 21, 2014, 03:35:30 PM »
I mentioned in an earlier thread the idea of making a framework that could fit into the microwave, to hold a spoon such that it would stir milk being heated as the turntable rotated. I have since made the framework and tried it twice. I have also come up with a way to expand the capacity of my simple yogurt maker. The pictures and descriptions below give the details.

Picture 1: the parts -- 1/2" PVC Schedule 40 pipe and fittings. Pipe segments were cut 7.5" to fit my microwave in height and width.

Picture 2: the framework installed in the microwave, with two plastic spoons zip-tied in place

Picture 3: another angle to show more of the assembled framework

Picture 4: Milk (2 quarts) has been heated to 180* F on high, then held at that temperature by heating on 20% power for 30 minutes. Now the bowl is placed in the yogurt maker. As can be seen, it is too big for the yogurt maker and its original lid ... so another random lid was used.

Picture 5: Towels contain the heat of the yogurt maker so that it will work with the oversize bowl. Note that I have successfully done this with an even larger bowl as well.

Picture 6: After 12 hours, the yogurt is finished. Now it goes in the fridge to cool and further firm up.

Picture 7: The lovely, thick consistency of the finished product

Now there's something you don't see every day.

For bringing fresh yogurt to the forum and a lovely photo essay, please accept this humble cheese. 8)

Let's ferment something!
Bread, beer, wine, cheese...it's all good.

Thanks! I am still tweaking the stirring mechanism to get the best results, but my two experiments thus far suggest that this will allow me to make some AMAZING yogurt with a minimum of fuss -- let the microwave do the work!

Using Fage Greek yogurt as the starter, I am getting incredibly thick results with no detectable "twang" even before straining -- in fact, I wouldn't mind just a bit more twang. After straining ... it is like eating ice cream!
