Preheat the oven to 375 degrees F.

Sprinkle the florets with salt and steam for 8 minutes until slightly tender but still firm. In a heavy sauce pan over medium heat melt the 2 tablespoons of butter. Gradually whisk the flour in to the melted butter until no dry spots remain. Pour the hot milk and hot half and half in in to the butter-flour mixture, whisking constantly until it comes to a boil. Continue whisking constantly for 1 minute until thickened and then remove from heat. Add 1 teaspoon of salt, fresh ground pepper to taste, 1 teaspoon of white truffle oil and 1/2 cup of the Gruyere, and 1/2 cup of Parmesan cheese.
