Take your savory pancakes to new heights with this easy souffle technique. Simply separate your eggs, whip the whites on their own and fold them into a cheesy mornay sauce. Unlike a traditional souffle, these pancakes cook quickly on your stovetop griddle.
Melt the butter in a medium saucepan over medium heat. Whisk in the flour to make a roux and cook until golden brown, 60 to 90 seconds. Slowly stir in the milk and cook, stirring constantly, until thickened, about 3 minutes. Allow the mixture to cool slightly, then stir in the Cheddar. Let cool to room temperature, then stir in the yolks and sour cream; set aside.
Meanwhile, whip the egg whites in a stand mixer fitted with a whisk attachment on medium speed until frothy. Add the cream of tartar and continue to beat on medium-high speed until the whites hold stiff glossy peaks, 4 to 5 minutes.
With a rubber spatula, fold one-third of the whipped whites into the yolk mixture and continue to mix until fully incorporated. Fold in the salt, baking powder and baking soda. Fold in the remaining whipped whites and mix until homogenous. Fold in the bacon and jalapeno
Heat a griddle or nonstick skillet over medium-high heat. Spray the griddle with nonstick spray. Spoon 1/4 cup of the batter for each pancake onto the griddle in a small circle; the batter should be thick and not run when you spoon it onto the pan. Cook until the pancakes are bubbly on top and brown on the bottom, 60 to 90 seconds. Flip the pancakes and cook until brown on the second side, about 1 minute more. Repeat with the remaining batter, lowering the heat to medium if the pancakes are browning to quickly.
Serve immediately, as the pancakes will begin to deflate. Garnish with a dollop of creme fraiche and a sprinkle of bacon and chives.
