When I smoked a brisket point on the Jumbo Joe last weekend there was about a pound and a half of flat still dangling on the side. I trimmed this off and decided to use it for hamburger.
A few days ago I got out this beautiful piece of meat, cut in into cubes and ran it through a meat grinder. I made two huge hamburger patties and seasoned with salt and pepper. These were going to be great!
I fired up my Jumbo Joe for indirect high heat. I had a charcoal basket of lit coals on the right side of the grill and placed the hamburgers on top of a GrillGrate panel on the left side of the grill. I placed the lid with the air vent (and thermometer) over the hamburgers.
I let the burgers cook for 15 minutes while the temperature of the Jumbo Joe slowly rose.
When the burgers hit 140F internal I pulled them from the grill and took them inside to dress them up. I was so danged excited! I had two monster sized fresh ground brisket burgers that were cooked to a perfect Medium….mmmmm!
And then I found out that we didn’t have any freaking hamburger buns.
And then I bit into a bunless burger and it was solid grey without a hint of pink.
And then I went outside and saw that the thermometer on the Jumbo had shattered.
I don’t know how I screwed up the burgers (sob!) but I do think I know what happened to the thermometer.
You can see in the pictures that there was some condensation inside the dial. I suspect that as the water vaporized at higher temperatures it turned to steam, built up pressure and blew out the glass. You can’t tell from the picture but it was very obvious that the glass blew outwards.
The thermometer probably got some moisture inside when I left my Jumbo Joe uncovered during a storm. On one hand, shame on me for not keeping things covered. On the other hand, this was a high end thermometer designed for use on a grill. If this guy can’t tolerate exposure to the weather then it has no business being on the market.
I am looking for input here. Does anybody else have experience with this brand of thermometer? Did I just happen to have a dud or is this a common problem?
By the way, if you need any parts to fix up your Jumbo Joe then here is a link that has what you need.
