Whole milk produces a bit more than non-fat and is also quite a bit thicker when finished. I like a really thick yogurt so I usually strain out a lot of the whey when I'm done. The whey strains out quicker in the non-fat than the whole, but again you're left with less of a yield that way.
Step 1: What you will need.
- a large pot
- a glass jar with a lid (sterile)
- a starter (can be a couple tablespoons from store bought yogurt with live cultures)
- a spoon (sterile)
- a candy thermometer (optional)
- a wash cloth (optional)
Step 2: Preparing the milk.
1. Pour milk into jar.
2. Put jar into pot of water on stove. Make sure the water line comes to about half way up the jar of milk.
3. Turn stove on high.
4. Periodically check milk until it reaches the temp of 185 F, or if you don't want to use a thermometer just wait until you can see tiny bubbles starting to form around the edges of the milk. It will also begin to form a skin on the top.
Step 3: Removing the jar to cool.
Also, take out your starter from the refrigerator while the milk is cooling to bring it up to room temperature.
I also turn my oven on warm at this point to make sure there is no temperature fluctuation while the yogurt is in incubation phase.
