Last winter, I complained that 70 degrees inside was not the same as 70 degrees outside because it can be 70 degrees inside and my butter is hard while when it is 70 degrees outside, the butter is soft.
I even bought a thermometer to prove it. Well, today is a great day for the test: It’s 71 inside, which is 70 degrees warmer than it is outside (yes, it’s only 1 degree out, today) and the butter is a rock.
I checked the temperature of something not attached to anything – a pendant light over the counter. It was, as expected, 71.2 degrees. Then I checked the butter temperature.

Not so much. It turns out that the countertops along the outside wall get very cold. The cabinets below them are closed, so the heated air doesn’t get under them, much. They’re also attached to the cold outside walls (the house is concrete block, for the most part). The butter dish, sitting on the cold counter top, is happy to pass that through to the butter.
That’s great for rolling out pie crust. Not so great in any other way.
Mostly unrelated: Definitely hot-tubbing tonight. I love it when the water is 100 degrees warmer than the air (without boiling me alive). Pro tip: Don’t directly touch the doorhandle on the way back inside.
