The only thing that saves your ass when the rubber meets the ice (and your car's stability assist fails) are your own lightning fast reflexes and loads of experience.
There can be the usual "do this when the car oversteers, don't do this when it understeers", but it's crucial that the beginner driver experiences it all in a safe and controlled manner. A parking lot, an old airfield, a safe road in the middle of nowhere. Literally the fun stuff we did behind our parents' backs. Pulling the e-brake on FWD cars, drifting the RWD cars, getting a feel for the different sounds of different surfaces under the tires. When doing this on snow and ice it's not even that hard on the car and it's fun and also educational.
A car sliding a bit on a snowy road when you've been expecting it is a non-event. A car sliding unexpectedly with a beginner behind the wheel is a terrifying experience and often a dice roll between stuck-in-a-snow-bank or a head-on collision.
