Break an egg in a bowl.
Add the salt.

Add the kefir and beat with the mixer.
Mix flour with baking soda, and add to the mixture.
Beat with a mixer on low speed. Leave the mixture on the table for 10 minutes.
Heat a non-stick pan, preferably a pancake pan. Do not use oil, the pan must be dry. Using a ladle, pour a little of the mixture into the pan. Turn the stove to medium heat.
After about 15-20 seconds, flip to the other side. The pancakes cook very quickly; be careful not to burn. When golden brown, turn them over.
Serve with honey, jam, chocolate, syrup, or fruit. Enjoy!
