    Using cooked meat or not, almost certainly not going to get hot enough to pasteurize and not airtight to prevent contamination.

    So…sounds like a perfect incubator for bacteria.

      I don’t know where this is but it doesn’t sound impossible to me. A quick Google shows that the FDA recommends 160 F for casseroles and that in direct sunlight a car can hit 160 if the ambient temp is >105 F. I know mailboxes aren’t cars, but over a longer period in a smaller metal box, it seems like the math could check out

        I live in Utah where it’s been sinfully hot and dry for the last week. I fully intend to test this theory. I just bought a high temp probe that should get here tomorrow. I will provide an update once the testing has been completed.

          Alright, I have the sensor installed. It’s a bit cooler and more overcast today, but I’ll hopefully be able to get some good data.

          A graph from Home Assistant showing the current temperature of the mailbox.

            I don’t know if this could inadvertently dox you but I’d be curious to see an hourly outside temperature too to see how much hotter a mailbox gets than outside. Based off your first graph here I’m wondering if cars having glass windows makes a greenhouse effect that would make a car hotter than a mailbox, everything else equal?

              Seems like a worthwhile thing to do! I’m not worried about doxxing, since someone would have to go to pretty extreme measures to correlate with the exact climate where I’m at. I installed the sensor after the hottest time of day had already passed, but here’s what it looked like:

              A graph showing the outside temperature versus the temperature in the mailbox.

              I’m pretty sure the spikes in the mailbox temperature were due to cloud cover.

                In my opinion this pretty conclusively proves that you can’t make a mailbox lasagna. This is the graph I looked but for my previous statement:

                A graph showing the temperature the inside of a car can reach in the sun

                And it shows that a car can hit 130-140 at temps around what you posted. Which is so much wildly higher than what you posted I do have to assume cars have some sort of greenhouse effect going that mailboxes don’t

                Finally when you consider how much of the total volume of a mailbox a lasagna covers, I have to imagine that’ll slow heating down even more! Great work!

                  As a follow-up, I have a new record temperature. Thanks, West Coast heat dome!

            By the way, just a quick tip, if you haven’t already maybe try airgapping the sensor from the metal with some foam so you’re measuring the air itself.

              I have it positioned right now so that the probe tip isn’t touching any metal, but I’ll probably add a bit of foam. I have some incredibly irritating foam packing peanuts that would probably work well. I’ll go do that now.

              EDIT: here it is, in all its gloriously crappy, uh, glory:

              a picture of a temperature probe poking into the inside of a mailbox. A Styrofoam packing peanut with a hole in it has been put over the probe to stop it from touching the walls of the mailbox.

        Unless your mailbox has a bunch of windows, you won’t be getting the big greenhouse effect

    Do we all understand this is meant as a commentary on climate change, and not an actual recommendation to use your mailbox as a cooking implement?

    …uh, folks?

    Oh look, I got a subpoena but it’s drenched in grease. And here’s a letter from Aunt Edna, also totally soaked. Mailbox cooking is the best though.

      I hope there’s no stray dogs in your neighborhood, or you might have trouble getting to your mailbox at all when you come home.
