Yogurt; How to make it the easy way.

I have a couple of hot/cold packs for a zippered pan traveling kit. Comes in very handy for housechurch potlucks. Anyway. I also have a small cooler. And the other day when I wanted to make yogurt agian I realized that the hot pack in the bottom of the cooler would keep them the perfect temp to make yogurt. And it does. I heat my hot pack in the mircowave for 4 minutes. While this is heating I take 4 quart jars and put about a tablespoon of yogurt starter (I buy yogurt that says 'live cultures' on it and use it as my starter) in the jars. Then fill with fresh milk that has not been cooled. Ididn't even have to stir it this way as the milk pouring in stirs it. Then I put the hot pack in the bottom of the cooler (heat rises), put my 4 quart jars of whole milk on top. I do put plastic wrap on the top of the jars. Then I pack towels in around and above the jars and close the lid. The next morning I take my cold pack which I keep in the freezer and I put it on top of the jars. That will cool the jars off enough that they will set. The nice thing about the cold pack (which I have to admit I did not think of. It was Papa) is that you don't have to move the jars at all which gives you a better consistancy of yogurt. Then I took the jars out that night, should have probably done it in the afternoon as the cold pack was barely cool, and put them in the fridge. YUMMMM. We add homemade jam to taste or strain it overnight to get a thicker greek style yogurt and then add jam or syrup to taste and dip fruit or what have you in it. Very good.
