Here's how to make oil from walnuts. I haven't done it yet, because I'm still searching for a nut/seed oil extractor machine. - Crack the walnuts.
- Grind the walnut meats in a standard meat grinder. Be sure to have a clean bucket or bowl underneath to catch the walnut meats after the first grinding.
- Using a big cast iron pot, cook the walnut meat with a little bit of water. Over a fire is fine. Takes about 30 minutes, constantly stirring, with a big wooden spoon or wooden paddle.
- Place the cooked hot walnut meat in a press.
- Here's the tricky part - you need to set up some kind of a press, with LOTS of strength and force with gentleness. You don't actually pound the walnut meats, just press them. Have a strong tray to hold the walnut meats, and a way to drain the oil from there to a waiting jar or bucket. NOTE: I've seen car jack hydraulic systems being used but I don't think I could do that.
- Seal and store in the fridge.
Sorry - this is the best I can come up with ... so far! I'm still searching for a nut/seed oil extractor. Anyone?
