In an Irish Coffee glass or similar, combine
1 tablespoon of honey
1/6 of a lemon (no more, not less)
1 clove (stuck in the rind of the lemon. Avoid the temptation to add more cloves)
1 shot of Jameson's Irish Whiskey (Bushmills doesn't work as well, apparently)
Fill to the top with boiling water
Breathe the vapors until it's cool enough to sip. Then, sip and breathe until finished.
Those of you who can't drink or prefer not to, I'd imagine you could get a similar, but not quite as fun effect by tossing some fresh ginger into boiling water and adding the remaining ingredients.
Now, I've not tried this myself, but mercifully it's because I haven't been sick enough in recent years to need it.*knocks frantically on wood* but if I do get the plague, i'll see if i can procure a fifth of Jameson and let you all know how it works.
