ghee + hot weather
I just got some ghee delivered and it's 100 degrees outside. The ghee is liquid and very very hot. I'm guessing it was sitting in a delivery truck all day today in the hot weather.
Is it stable or gone bad?
Haw well the ghee is stable when cooking at several 100 degrees, so my assumption would be that being at a semi-hot temperature for a long period of time doesn't damage it (I assume it endured high temperatures in the climates where it is traditional also)
It is stable - its basically pure fat. Microbes need water to grow which is why you render the fat from meat to remove water. No water = no spoilage. One method of preserving food was to basically store it in a jar of rendered fat.
