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.
Simmer the brats until they reach 165 degrees Fahrenheit in the center, about 5 to 10 minutes according to their thickness. Reserve the cooking liquid. Heat a few tablespoons of butter or oil in a pan over medium heat. Dry the brats with a paper towel and saute them until the casing crisps, about 4 to 5 minutes. Combine the pan drippings with the cooking liquid and simmer it until syrupy for a simple reduction sauce.
