In relativity theory, Einstein introduced mass as a new type of energy to the mix. Beforehand, the mass of something in kilograms was just a measure of how much stuff was present and how resistant it was to being moved around.
Set the broiling pan in the oven once the broiler has warmed up. Make sure the sausage is positioned about seven to nine inches below the heat. Cook for 16 to 20 minutes total, turning the brat 90 degrees every four to five minutes so that it cooks evenly on both sides.
Turn the brats every 5 minutes. After 5 minutes have passed, open the oven and use an oven mitt to hold onto the broiler pan. Use tongs to turn over each brat. Put the pan back in the oven for another 5 minutes, and then turn the brats again. Cook the bratwurst for a total of 15-20 minutes.
