Prepare the Batter
In a large bowl or mixing bowl, whisk wet ingredients: kefir and egg.
In a separate bowl, mix dry ones: flour, sugar, salt, baking soda.
Using the Two Bowl Method keeps the batter smooth without lumps.
Combine wet ingredients into dry ones. Stir gently. Do not overmix. The thick batter should look like dense sour cream.
Let Batter Stand (15 Minutes)
Let the batter stand for 15 minutes. This helps activate baking soda. You will see bubbles form and the batter thicken. This active batter will rise better during cooking.
Heat the Pan
Use a non-stick pan or skillet on medium heat. Add oil about 1 cm / 1/3 inch deep. Avoid grapeseed, canola, palm vegetable oils. Neutral oil avocado oil coconut oil works best.
Fry
Use a large spoon, small ice-cream scoop, or heaping tablespoon. Pour 1 to 2 tablespoons per pancake.
Cook 2 to 3 minutes until bubbles form on the surface and bottoms turn golden-brown. Flip carefully halfway through using two spatulas to avoid splash.
They should double in size and become tall and puffy. Fry in batches, about 5-6 pancakes at a time.
Finish Cooking
If worried about uncooked centers, place them in a 375F / 190C oven for 5 minutes or 7-10 minutes in a 400 degree oven. Use an oven proof dish.
