*250g of butter, yields 1 cup of ghee. If you use more butter, you'll have more ghee!
The whole process to make ghee takes 20-30 minutes. Please read all the instructions before you begin to make the process run smoother. I recommend using a stainless steel pot so you can clearly see the bottom of your pan and can easily determine when you've got ghee because you'll see the little brown bits at the bottom.
