Put 2 spoons of flour into lukewarm milk. Add sugar and yeast. Set aside until it moves (app. 15 minutes). Put the remaining flour into a bowl, add the remaining ingredients and the yeast mixture. Mix until smooth. The batter should be slightly thicker than that for pancakes. Set aside to rise for about 1 hour.
In the meantime peel the apples and grate them. Optionally chop into small pieces. Put the apples into the rested batter. Mix. Spoon the batter onto a frying pan with heated oil. Fry for app 3 minutes on each side. Be careful not to burn these delicious treats! Leave to rest for app. 1 minute. Serve sprinkled with icing sugar.
