Hey, bflat: you hold the answer to your headcold right here. Getcha some salsa, or just down a few jalapenos -- the little rascals have more vitamin C per punch than a basket of oranges. (I always top it off with a shot of Bushmills, too, of course...Sleep like a baby and wake up with clear sinuses!) Chili peppers have some vitamin C; habeneros are really loaded, but they also blow the top of your head off -- see Spaw's recipe. Suggest jalapenos as a happy medium.
