The application is simple: Activate the steak and the Champ - Prick steak laterally centered - at least 3 cm thick (!). The desired cooking point is indicated by flashing in 3 colors: green = medium-rare accordingly 50-52 ° C, Yellow = medium according to 58-60 ° C and red = medium-well according to 65-67 ° C. In the latter doneness but it's a pity for steak and suitable only for the "yuck-not-so-bloody-fraction" I myself prefer medium-rare. ;-) When double flash of LED, in the desired degree of doneness, take rest and the steak from the "fire" can be until the LED goes out. This point is extremely important, so that the steak "relax" may.
If you have several steaks from the same caliber (height and weight) at the start, so you can take a reference. That works very well as long as the Grillglut uniform.
Dear something less but higher quality meat, so my motto. It takes no time to puzzle over the degree of cooking and make supposedly safe "pressure tests"! The steak is made simple always. A small optical downside is the hole in the steak, which remains after the drawing of the "Steak nail".
The Steak Champ I also have a previous version, which is designed for only a certain degree of doneness. People suffering from a severe color vision deficiency and is on his Wunschgargrad clear, maybe you should pick up the monochrome predecessor, eg Steak Champ variant medium-rare or medium-rare example set of 2 & medium.
I would recommend the product and just the barbecue season it is also a surprising gift.
