Fluffy kefir pancakes

The secret to their height: warm the kefir, then leave the batter to rest for 20 minutes after mixing and do not stir it again.
Ingredients
- kefir 3.2% — 500 ml
- egg — 1
- sugar — 30 g
- vanilla sugar — optional
- salt — a pinch
- flour — 400 g
- bicarbonate of soda — 1/2 tsp
- sour cream — to serve
- jam — to serve
Method
- Warm the kefir over a low heat without letting it boil — just to the first bubbles.
- In a bowl, lightly whisk the egg with the sugar and salt.
- Pour the kefir into the egg mixture in a thin stream, whisking.
- Add the flour in stages. The batter should be quite thick.
- Add the bicarbonate of soda, stir, cover with a towel and leave for 20 minutes. Do not stir again.
- Fry over a medium to low heat, uncovered on the first side and covered on the second.
