Which Biblical verse indicates the separation of milk and meat?
‘Thou shalt not seethe the kid in its mother’s milk’. Objective meaning of this verse is debated, however. More on mixture of milk and meat here.
What terefah means?
Terefah is the opposite of kosher. A meat that is forbidden to eat for some reasons.
Apart from using salt to withdraw blood from the meat is there any other method?
You can place the meat on a grill over flames until the meat is half done. Collect dripping in a pan. The grill and pan must be used only for kashering meat.
I consider salting better.
