Following on my last BBQ experiment, I did a google on how feasible it is to retro fit my Weber Kettle with a grill thermometer. Note that I already have a meat thermometer, but the idea of the grill meter is to measure the actual temperature of the grill when using it with the lid on.
Anyway, while researching this, and costing grill thermometers (which are not very expensive at all), I came across a wireless meat thermometer going cheap on eBay. Unlike normal meat thermometers, which are used to take spot readings, this is left in the meat while it is cooking, and gives a voice alert when the food is ready. They normally go for 35-50 quid in the UK, this one had one bid on it only. In the end, I picked it up for 5.50 plus postage, new and still in the box.
This isn’t actually what I was looking for, and I think I still need a grill thermometer too. However, this was too good a bargain to miss.
