Hi madhuri,
Preparing ghee at home is quite easy. Look for unsalted butter in the stores. So far, I've used
Land-O-Lakes unsalted butter, Kirkland butter and Trader Joe's. All are of good quality. So, choose the one you want and proceed.
The butter can be refrigerated if you use it often or best bet will be to freeze it.
Preparation of Ghee:
Take the required amount of butter and add them to a hot pan.
Keep the heat to medium-high.
The butter slowly starts to melt and keep stirring it every now and then.
After a few minutes, it starts to bubble with noise. Keep stirring it and wait for the noise to subside.
Once it starts foaming on top, reduce the heat to med-low.
The cue is to wait for the golden brown colour (it should not be white or yellow) and switch off the heat at that point.
Remove the pan from heat, wait for sometime.
Then filter the ghee using the stainless steel filter and transfer it to another container.
To start with, try with 2 sticks of butter. If it comes out right, then you can prepare a little more. :)
Do try and let me know. Good luck!
