Maybe it is mamster, I bought a thermometer for my kitchen, I found the temp in the kitchen at 23ºC when I was working, it that hot? What about breezes, hot or cold, could that effect the chocolate while it is setting? Another thing, I got a good temper, within 5 minutes the chocolate set, my question is why did the remaining chocolate have small specks all over the top after it set?( I think it is call "bloom"). The truffles I dipped also had them, but not very noticable. Why does that happen, this has been my biggest problem for so long. Anyone PLEASE help.
