Using a whisk, mix the eggs with the salt, then with the kefir or yogurt.
Mix flour with baking powder and add it to the egg mixture, incorporating until we obtain a creamy composition.
Heat a pan over medium temperature, grease it with butter or oil, add a small ladle of batter, wait 1 minute or until bubbles appear on the surface of the pancake, then add the mozzarella and cover it with more batter.
Turn them over and wait another minute.
Enjoy them warm with sweet or savory toppings.
Bon appétit!
