Making ghee/clarified butter is a process that achieves the following things:
-remove water from butter
-remove solids that brown and impair a bad taste
To remove water you need to reach a temperature close to 100°c to evaporate it, so a slow boil will be necessary
Here's how I've been taught to make ghee by an indian chef:
-Gently heat butter to melt if, and scoop out the solids with a spoon of pour through a fine cheesecloth / sith
-bring to a very gentle boil. That will evaporate the water. Keep scooping up whatever solids form up
-Once bubbling has stopped, most of the water is gone. To test for the presence of water, dip a small strip of paper in the butter and light it with a flame. If the flame burns clean like a candle, the ghee is ready. If there are any snaps, crackles and pops in the flame there is still water in the mix so keep heating the butter
The resulting fat can be kept in a fridge for weeks
Bottom line: no two ingredients are exactly alike, except for chemicals that are 'analytical grade', so there will always be some adaptation required in cooking, no matter how much science you throw at it
