In a bowl, whisk together the flour, sugar, salt, baking soda, and baking powder. In a separate bowl whisk together the egg yolk, melted butter, buttermilk, and milk. Add the wet mixture to the dry mixture. Stir gently with a wooden spoon until just combined. It's good if the batter is still a bit lumpy. Gently fold in the egg white and chocolate chips.

Heat a large, flat skillet over medium heat. Put a small amount of canola oil in the pan. Drop 1/4 cup amounts of batter onto the pan, giving it space to expand. Cook until bubbles appear on the surface. If you'd like to place the strawberries in the pancake, layer the slices on at this point. Flip the pancakes and cook for another few minutes or until golden on both sides. Serve with slices strawberries, whipped cream, and syrup.
