Separate the egg whites and egg yolks into two separate mixing bowls, being careful not to break the yolks. Whisk the milk, vanilla, and lemon zest into the egg yolks until combined. Sift in the flour and baking powder, then whisk until smooth with no visible dry flour. Set aside.

Add the vinegar or lemon juice to the bowl with egg whites. Using a hand mixer, beat on medium speed until completely frothy. Gradually add the sugar a little at a time, then increase speed to medium-high and continue beating until stiff peaks form.

Add ⅓ of the meringue to the egg yolk mixture and gently fold with a rubber spatula until evenly combined with no visible streaks. Add the remaining meringue and fold gently until just combined. Do not overmix or the meringue will deflate.

Heat a large nonstick pan over low heat and lightly grease with oil, wiping away any excess. Portion the batter into the pan to make 2-3 pancakes using a large spoon, cookie scoop, or piping bag, keeping the batter mounds tall. Cover with a lid and cook for 7-8 minutes until the bottoms are golden brown.

Gently flip each pancake and cover again with the lid. Cook for another 5-6 minutes until golden brown and cooked through.

In a mixing bowl, combine the cold heavy cream, sugar, and vanilla. Whisk by hand or with a hand mixer on low speed initially, then increase to medium until firm peaks form. Refrigerate until serving.

Serve the pancakes immediately, topped with sweetened whipped cream, fresh berries, a dusting of powdered sugar, and/or maple syrup as desired.
