Microwave the kefir and water together for 30 seconds until warm. In a bowl, whisk together the egg, salt, and sugar. Add warmed kefir mixture and stir. Gradually whisk in flour until smooth, fold in baking soda and chopped apples.

Heat a non-stick skillet over medium heat and add neutral oil. Allow the oil to warm until it shimmers.

Drop dollops of batter onto the skillet, leaving space between each pancake. Cook for 2-3 minutes until edges are set and bottoms are golden brown. Flip when bubbles form.

Gently flip pancakes and cook for an additional 1-2 minutes until golden brown. Adjust heat as needed for the next batch.

Transfer pancakes to a plate and serve warm with toppings like honey, sour cream, or jam.
