I raced bikes for a very long time (think sprint athlete) and we would do a lot of things for recovery that I've found to translate well to recovery after skiing. Skiing-wise, I tend to alternate between blowing off recovery (and paying the price the next day or two) or focusing on recovery and then feeling pretty good in the aftermath.
The first doesn't work well for everyone (allergies, etc), but pounding down a pre-made 8 ouncer of Muscle-Milk (available in convenience stores) can drastically help if you get one on the ride home from the mountain.
There's no substitute for diet though, and a balanced one is always a great idea. Stay hydrated, don't eat a lot of crap, and the rest will take care of itself. Eat a banana or two also.
I've got buddies that swear by ice baths, but I'm all set with that. Not going to dip the boys in ice water after recreational skiing.
If you're "feeling the burn" on the mountain, take a break and walk/shake it off. Breathe deeply. The burn is lactic acid. It builds in your muscles as your fitness (heart/lungs/blood oxygenation capacity) diminishes. If it's left to hang out in there, it works against you. Walking it of while focusing on your breathing helps to flush it out.
Rule of thumb: if you're in pain, don't exercise again until it's gone.
