Foods to eat to help soothe strep throat pain ?

My grandmother's method was to make a cup of hot water or tea with a tablespoon or two of both honey and lemon juice (equal amounts of both). Honey is a natural antibiotic (which combats strep throat) and coats your throat. The lemon juice contains vitamin C and also seems to help. It's always worked for me.

Ginger tea with honey works for me.  Take fresh ginger, skin it, slice it up, pour boiling water over it, let it steep, add some honey, and voila.
