How to make
Beat the eggs with the sugar, add the oil and yoghurt. Sift the flour with the baking powder and add them to the mixture.
Set aside 1/3 of the mixture, put the cocoa in it. Pour the white mixture into paper muffin forms, pour in a little of the brown mixture over it.
Put pieces of chopped chocolate in each muffin, as well as chopped candied orange rinds and 1-2 sour cherries from the jam.
Bake the muffins at 360°F (180 °C) for 20-25 min.
