According to my grandmother (and probably her grandmother as well), this combination of "four elements" is the best to prevent you from being sick.
Preparation is dead-simple, just warm up the milk, put it into a container (preferably something not transparent, mug is perfect; you don't want to see it really, but get it down the hatch really quickly). Add 2-3 spoons of honey and butter (which melts and adds lovely golden color to it as fat goes to the top). In the end, chop & squash 2-3 pieces of garlic, add it and let it "get the flavor" for couple of minutes.
Effect guaranteed. It is either the unique combination of natural substances plus fatty consistence that really soothes your sore throat or some help from subconsciousness ("Don't do it to me, man! You can't drink it twice, !!!")
