Ok, I changed my mind. I went out looking for a coffee grinder and only found grinders that grind LARGE amounts of "coffee". So, I bought a pepper grinder instead. The ground weed is almost dust, so I think it'll work just fine. Anyway, while at the store I looked at crockpots and found a digital one with a "probe" that I can place in the oil. So, I can guarantee the temperature in the oil. Last night I put the crockpot on high with an oven thermometer inside and the temp was a hair above 250, so I probably don't even need the probe. I will be cooking tonight and testing tomorrow.
