Preheat broiler or oven to 425 degrees
Trim Cauliflower, Slice medium thin sliced thickness, about 1/4 inch, not shaved
Use a small cast iron pan that will make three layers.
Heat clarified butter in pan. To make clarified butter, heat in medium heat and skim off all foam. What is left is clarified butter.
Add cauliflower one layer at a time, not to crowd pan. Fry until nearly golden brown or golden on edges. Remove to dish, as you cook each layer.
Season each layer with salt and pepper. Make sure each layer has some of the melted butter.
Layer each with a parmigiano reggiano cheese.
Save the nicest cauliflower pieces for the top.
Sprinkle top with cheese.
Either roast at 425 for about 10 minutes, until the cheese is golden, or place under broiler for about five minutes. You may need to watch this closely to not burn it.
When it comes out of the oven, sprinkle chopped parsley or basil.
