We are holed up in Barcelona today. Three of the four of us have horrid colds. My mom went out for fruit and rolls and I just finished making our version of cough syrup.
I brew a pot of really dark black tea, cut up and squeeze two whole lemons and drop them in to seep, and then add cloves and sweeten with honey.
Heat breaks up the crud, lemon and honey soothes the throat and cloves numb it all up. The caffeine seems to make everything feel a bit less punk.
I would use brandy instead of whisky ; -)
