Put the butter into a good quality pot (without a lid) and heat on medium to high until the butter begins to melt
When the butter is melted, reduce the heat so it is slightly bubbling and continue to simmer for about 15 minutes
Using a clean metal serving spoon, skim the white foam off the top and discard in a separate bowl
Stir occasionally to ensure it doesn’t burn or stick to the bottom of the pan and continue to occasionally skim the foamy white milk solids as they appear
After another 10 minutes or so, the remaining white foam will begin to solidify into curds and you will see the clear golden liquid beneath
When the curds begin to turn a golden colour, the ghee is ready. It should also start to smell like popcorn!
Let the ghee cool and the curds will sink
When it is at a safe temperature, pour the ghee through a fine strainer or muslin cloth into an clean, airtight jar
