If you are ever unsure about the quality of your ghee, here are some easy tricks you can bookmark and refer to the next time you have a doubt.

One of the simplest measures is to heat a teaspoon of ghee in a vessel. If the ghee melts immediately and turns dark brownish in colour, then it is of pure quality. However, if it takes time to melt and turns light yellow in colour, it is best avoided.
