Take the 1.5" medallions out of the fridge 30 minutes ahead of time.
Sprinkle with salt. Make a mixture of red chilli powder, coriander powder and cumin powder. Dredge the medallions in the mixture and set aside.
Melt 1 tbsp of butter with 1 tsp of olive oil in a skillet. As soon as the oil starts smoking, put the medallions in. Cook for no more than 4 minutes per side. Remove and tent with foil.
For the pan sauce, take the pan off the flame, remove the remaining fat and add 1/3 cup cognac. Ignite it and shake the pan till all the flames die off. Add 1 cup of heavy cream and return to heat to thicken so it coats the back of the spoon.
Ohhh yummmmmm.....
