When I learned to fly gliders we practised spins and spin recovery. First time I did it, I botched the recovery and was mildly terrified. Went up a week later with a extremely experienced instructor and spent a whole hour thermalling up to altitude, stalling, then using the rudder to kick it into a spin, cancel the rotation, kick it into an opposite spin and back, stalled the whole time. Lose 3000 feet, recover, thermal back up, do it all over again. Very interesting to feel the complete ineffectiveness of the ailerons vs very effective rudder. By the end of it, I was pretty confident I would recognize the symptoms early and had the muscle memory to react quickly and correctly if I ever needed to. Best flying lesson I ever had. Of course all that is with no engines. Assymetric thrust in a twin is more complicated, and I expect you've got less margin before you damage the airframe.
