1 Bake in the preheated oven until the meatballs are tender, about 40 minutes. Remove meatballs to a serving dish.  To make brown gravy, pour pan drippings into a saucepan over medium heat. Whisk the flour into the pan drippings until smooth, and gradually whisk in enough beef broth to total about 2 1/2 cups of liquid.
Room Temperature. 28 pages on this wiki. Room Temperature (RT) is generally defined as the ambient air temperature in whatever environment being used for a given procedure. More specifically, it is defined as 20-25Â°C (68-77Â°F), as some ambient temperatures, by nature, do not fall within this range.oom Temperature. 28 pages on this wiki.

This temperature difference is called a Celsius temperature, symbol t, and is defined by the quantity equation t= T-T0. The unit of Celsius temperature is the degree Celsius, symbol Â°C. The numerical value of a Celsius temperature t expressed in degrees Celsius is given by t/Â°C = T/K - 273.15.
