In a bowl, mix the flour with the remaining dry ingredients.

Add the egg and pumpkin puree to the bowl.

Mix thoroughly with a kitchen whisk.

If the batter is too thick, add kefir in portions – it should be thick but slightly pourable.

Set the bowl of batter aside for about 15 minutes – air bubbles should appear on the surface during this time.

Lightly grease a small frying pan and preheat over medium heat.

Pour the batter onto the pan and spread it out evenly.

Cover the pan with a lid and cook the omelet over low heat for a few minutes.

Carefully flip the omelet over, cover, and fry the other side for about 1–2 minutes.

Remove the omelet from the pan and serve with your favorite toppings.
