Ghee differs from European-type clarified butter in one important respect: when you make clarified butter, you let all the water simmer off from the butter, you skim the solids floating on the top, then you pour off the butter fat from the solids that have sunk to the bottom. To make ghee, you simmer for an hour or two more, until the solids on the bottom have browned (caramelized, but not burned), and THEN you skim off any floating solids and pour off the pure butter fat. The result is butter fat with a touch of a nut flavor to it, compared to European clarified butter.
Both clarified butter and ghee can be heated to deep-frying temperatures without burning.
As long as it doesn't get damp, freshly made ghee keeps almost forever at room temperature. Used ghee (i.e., drained and filtered after being used for deep-frying) will keep almost forever if refrigerated. Like all oils or fats, if it's exposed to enough moist air it will go stale or rancid.
Ghee is THE traditional staple frying fat of Northern Indian cuisine. It IS a saturated fat, so if you have dietary concerns about that, ghee isn't for you. But let's face it--butter fat tastes good. It's why a lot of the dishes in French haute cuisine skim off and discard the fat that naturally arises from the foods being cooked and substitutes a butter fat in the final sauce.
And it's about the easiest thing in the world to make. Just take a large quantity of butter (one pound or more), melt it over moderate-low heat until it is just simmering, then let it sit for four hours. The only way you can go wrong is if the heat is too high and you burn the solids. A thick-walled pan (heavy copper lined with stainless steel is ideal; cast iron or ceramic-lined thick aluminum is also good) helps keep things under control.
