Think of it. Whenever you want to cook something and make it taste great isn't butter your go-to ingredient? After I learned that saturated fat does not harm our health (link included below to the proof)I have been using beef tallow, coconut oil, and now ghee to deep fry. I've always fried seafood in butter, but French Fries and crab cakes in ghee should be the best I've ever had. For your reference four pounds of butter yielded 1 3/4 quarts of ghee. This is the best website I found for how to make ghee from butter:
