I don't think extra food will help you "goose" recovery unless you are calorie restricted right now. I do think hydration, frequent BCAA dosing, and active recovery techniques (contrast showers/ice baths/compression cuffs) can be useful if training frequency is high. Overall, I don't think there's much to do that will decrease soreness outside of the water and BCAAs.
B alanine is useful for intraworkout fatigue, but not necessarily recovery from training over the course of many hours. Creatine is obviously useful, as is betaine anhydrous, HMB, and L-Carnitine Tartrate.
