In a bowl, combine flour, maple sugar, baking powder, and salt. Set aside this first mixture.
In another container, combine melted butter, buttermilk, and eggs. Gradually add this second mixture to the first, then fold in the stiff egg whites, grated cheddar, and prosciutto strips.
Cook in a waffle iron.

Sauté the pears in butter and add rosemary.
Finish cooking with maple syrup. Don’t overcook to preserve the crunch of the pears. Pour this topping over the waffles.
