Hi friends!
I’ve had a topic that I’ve wanted to cover for a while and seeing how this has been the week of bizarre weather extremes in Colorado (record heat on Monday, then snow yesterday and near record lows this morning), I figured it’s the perfect time to talk about TEMPERATURE! But instead of outdoors, I’m talking about in some of your appliances!
When I work in a client’s kitchen, the first thing I do when I’m there is test the accuracy of their oven. The last thing I want is to burn their food if I think I’m cooking something in their oven at 350° only to find out that it’s actually much higher than that. You’d be surprised how the dials tell a completely different story than the actual temp inside your oven.
You can find an inexpensive hanging thermometer that you can pop right onto a rack in your oven and leave it there.

You can also determine “hot spots” in your oven this way as well by moving it to different locations. This would explain why that batch of cookies you made burned on the back right side of the cookie sheet and the front left ones were perfect.
You’ll find that if you have a convection oven the temp may jump around a bit as the fan turns on and off. If I set my oven at 325° often times it actually registers on the thermometer at 350°.
It also helps you to know if your oven preheats in the amount of time it says it does. Just because your oven beeps that the oven has reached the desired temp doesn’t actually mean it has. I’ve had some client ovens signal preheated when still 100° away. So place your thermometer and then compare. Is it at the expected temp when it tells you it’s ready?
Don’t just stop at your oven though. Do you have a toaster oven? I do. And I used to make the mistake of trusting the dial on the front. Until something came out of it TOTALLY charred (and not in that tasty ‘blackened Cajun fish’ kind of way). It hadn’t occurred to me until then to check my toaster oven and BOY was it ever OFF. I’m talking almost 200 DEGREES off. I thought I was cooking at 325° and it was over 500°!
Another good appliance to test is your dehydrator, if you have one. Many raw food enthusiasts use dehydrators to dry their food below certain temperatures in order to preserve the live enzymes in the food. (Depending on which expert you follow, some say that is below 105°, some say 114°, and others say below 118°.) So if you want your kale chips dehydrating at 105° and they are actually at 130°, you no longer have raw chips.
My dehydrator’s dial is anything but accurate when it comes to determining where the white dot actually is on the temp range. In this photo, I’d figured I was set at about 108°:

But I was actually much closer to 120°:

To test your dehydrator, rather than using an oven thermometer you’ll want to use an instant read thermometer that will give you a smaller range.
And last but not definitely not least, you should also check your refrigerator and freezer temperatures rather than trusting what the built-in appliance thermometer may be telling you. A recent job I was on found me working with a fridge/freezer that just didn’t want to stay as cold as they should. In the Food Safety world there is something called the DANGER ZONE that you don’t want your food sitting at for too long and that’s between 40° and 140°. In that range bacteria can multiply in phenomenal numbers. So you want your fridge to be under 40° but not freezing (ideally 33-37°). And ideally your freezer should read at 0-3°. Otherwise you might have a few million (billion, trillion) more ‘guests’ joining you with dinner than you may have anticipated!
Do you check your appliance temperatures on a regular basis?
