A spoonful of honey (or two) is a good remedy for a sore throat, however you won't want to eat much more as it will burn your throat after a certain point. Milk is always a good cooling remedy for throats, and tea will work nicely as well (you can even put the honey in either of these and it will help nicely).
Traditional remedies for flu include eating a load of onions/garlic as these force the spirits of illness out of our bodies. However, as much as these made me stink, whenever I've been sick and tried it I've only found it good for a quick clearing of the sinuses. You can also put a few fresh onions or garlic in the corners of the house or in the doorway as a way to prevent the illness from coming in.
I wouldn't really rely on the remedies to get rid of the flu, I would just wait it out. The good news is that now you'll be immune to that particular strain of the flu virus. :)
