olive oil tends to become one with the stuff that pulls out. i have always had a habit of saving stuff and looking at it later. the glass i spit out into would stay the same with olive oil. when i used corn oil a couple of times, the stuff would precipitate out of the oil and collect on the bottom of the glass. it looked like curds or something and smelled like baby burp. i figure it was a lot of dairy i was doing. and i was drinking only organic milk at the time. i have since found it is all poison, except maybe totally raw from a grass fed cow. i gave it up. maybe i can have a cow someday!
