I'm somewhat wary of the lard sold here. I suspect it might be hydrogenated even though it is sold refrigerated. Ghee is available at the local bio store but is somewhat expensive (and that's not even grass-fed), so I decided to try my hand at making my own.
After a long, involved self-tutoring process, which mostly consisted of watching this video, I felt I was ready. By the way, the guy in the video is a great example of all the wonderful health benefits of a vegetarian diet--nice man-tits, dude, but he does seem to know how to make ghee. And I envy him that big ole hunk of New Zealand butter he uses.
This is somewhat messy and time consuming, so a really large batch would be better, but for my first time I just started with 1/2 kilo of butter.
I scraped the bottom of the pan with a spatula to prevent any of the heavy particulates sticking to the bottom and burning.
Emptied it through a sieve, which didn't do much because it is a crap sieve.
Tried a cloth which was something of a disaster. I don't think it is really necesary to use a filter actually, next time I think I will just use the panning-for-gold method.
Finished product. After the reduction and all the spilling I ended up with about 300 grams of the stuff. Which makes the stuff in the store not all that unreasonable but I think I will stick with the homemade stuff and hopefully get better at making it.
