I'm a Ghee convert as well. I normally use a good olive oil when cooking at home. Sometimes however I like a little butter in a recipe. Ghee takes the high heat, eliminates much of the "bad" about butter, and on a trip is far easier to pack and use than oil, much healthier than Crisco type products.

I make mine with a small pan with a pouring lip, but heating the butter till melted and using a gravy fat device, is a very clever idea, one I'll try next time I need a batch.
I don't know about the Ghee in your coffee, but over oatmeal or baked/fried goods, it can't be beat. I like a shot of homemade Kahlua in my coffee/cocoa, brings out something for sure ;D

If you still want to bring some olive/canola/peanut oil, a little Ghee mixed in will give whatever your cooking a richer, flavor ;)
