Chamomile tea with honey works well for us for lightly sore throats. But the most unbeatable remedy that works every time is a Himalayan Sea Salt gargle (1 cup water, 1 teaspoon salt). Though I hate doing it, but it has cured the worst sore throats, even one where I couldn't swallow and my throat seemed like it was closing up. I didn't want to go to the doctor, so I gargled with the salt water every 4-5 hours or so, the pain went away in about 24 hours. That is the quickest fix I can recommend, and it's best do to it early, but it works regardless of how bad it gets! I also recommend Boiron Chestal Honey (Homeopathic Cough Syrup).
