In the last installment of my ongoing adventures making clear ice at home in the freezer, I found that using a hard-sided Igloo cooler works pretty well to create large, mostly-clear blocks.
I was curious to see if faster frozen blocks (with the freezer turned to its maximum cold setting) would come out more or less cloudy/clear than blocks frozen at the minimum cold setting.
Of course, my freezer isn't exactly high-tech. According to my novelty jumping bass fish thermometer I picked up in Finland (thanks for the trip, Finlandia!), my freezer only ranges from -3.2 to 2.2 degrees Fahrenheit.
Anyway, as you can see below, there wasn't much difference at all. Here's the block set on the warmest freezer setting (slowest to freeze):
And here at the coldest setting, which froze faster:
My finger (I should be hand model, right?) indicates where I'd cut the block to get rid of the too-cloudy ice. One was 12 cm and the other 12.5. At that difference, you may as well turn the thing all the way up and have your ice sooner.
