Have all the ingredients at room temperature. Preheat an oven to 200°F. Preheat a Belgian waffle maker according to the manufacturer’s instructions. In a large bowl, whisk the egg yolks. Whisk in the buttermilk, melted butter and vanilla. Over a sheet of waxed paper, sift together the flour, cinnamon, baking powder, baking soda, the 1/4 tsp. salt and the granulated sugar. Add the flour mixture to the yolk mixture and whisk until smooth. In another bowl, beat the egg whites until stiff peaks form. Using a rubber spatula, fold half of the egg whites into the batter, then fold in the remaining whites. Cook the waffles according to the manufacturer’s instructions. Transfer to a baking sheet and keep warm in the oven. In a fry pan over medium-high heat, combine the brown sugar, maple syrup, butter and 2 pinches of salt. Heat the mixture, stirring when the butter begins to melt. Continue to cook, stirring, until the syrup is smooth, about 4 minutes, then stir in the pecans. Remove from the heat and spoon the syrup over the waffles. Serve immediately. Serves 8. http://www.williams-sonoma.com/recipe/praline-waff...
