Step 1: Make the Pancake Batter
- Separate the eggs: Carefully separate the egg whites and egg yolks into two different bowls. Make sure the yolks stay intact and do not mix with the whites, as this can interfere with the whipping process.
- Mix the egg yolks: Into the egg yolks, add the milk, vanilla extract, and optional lemon zest. Whisk everything together briefly until combined.
- Sift in the dry ingredients: Sift in the flour and baking powder into the egg yolk mixture. Whisk until smooth and there are no visible streaks of dry flour. Set the mixture aside.
Step 2: Prepare the Meringue
- Whip the egg whites: Add the vinegar (or lemon juice) to the egg whites. Using a hand mixer or stand mixer, beat the egg whites on medium speed until frothy.
- Add the sugar: Gradually add the granulated sugar, a little at a time, to the egg whites while continuing to beat. Once all the sugar is added, increase the speed to medium-high.
- Beat to stiff peaks: Continue beating until the egg whites form stiff peaks—when you lift the beaters out, the peaks should stand up straight without falling over.
Step 3: Combine the Mixtures
- Fold the meringue into the egg yolk batter: Gently add one-third of the whipped egg whites into the egg yolk mixture. Use a rubber spatula to fold the meringue into the batter. Be gentle to avoid deflating the egg whites. Repeat the process with the remaining meringue, folding it in until the batter is smooth and no streaks of meringue remain.
Step 4: Cook the Pancakes
- Prepare the pan: Heat a large nonstick pan over low heat. Lightly grease the pan with a bit of oil, then wipe away any excess to avoid greasy pancakes.
- Note: An electric stovetop is ideal for this recipe, as it maintains consistent low heat. If using a gas stovetop, be sure to cook the pancakes over low heat to avoid burning them.
- Spoon the batter into the pan: Using a large spoon or a piping bag with a large round tip, portion the batter into the pan to form 2 to 3 pancakes. Try to keep the batter tall, as this helps the pancakes rise and maintain their signature height.
- Cover and cook: Cover the pan with a lid and cook the pancakes for 7 to 8 minutes, until the bottoms are golden brown. Gently flip the pancakes over and cover again. Cook for another 5 to 6 minutes, until they are golden brown and fully cooked through.
Step 5: Serve and Enjoy!
- Serve the pancakes: Carefully transfer the pancakes to a plate and serve them immediately. Top with your choice of sweetened whipped cream, fresh berries, powdered sugar, or maple syrup.
- Optional sweetened whipped cream: To make the whipped cream, simply combine the cold heavy cream, sugar, and vanilla in a mixing bowl. Whisk by hand or with a hand mixer until stiff peaks form. Keep refrigerated until ready to serve.
