Looking for suggestions on the best technique for "simmering". I set up an old electric fry pan as a double boiler with my slacum oil in a canning jar. I used a candy thermometer as a stir and temperature indicator for the slacum oil. Only achieved about 200F. I am going to try a reheat but I am little gun-shy (no pun intended) after a thermal event in the basement with a similar mixture and a heat gun.
