Crumble the yeast, mix with 1 teaspoon sugar and 100 ml milk. Cover and leave to rise in a warm place for about 10 minutes. Put flour, fat, salt, 95 g sugar and 200 ml milk in a bowl. Add the predough and mix with the dough hooks of the hand mixer to a smooth dough. Cover and leave to rise in a warm place for about 45 minutes until the dough has doubled. Finely chop pineapple, apricots and orange slices and knead with marzipan.
Grease a baking tray with 9 troughs in an egg shape (muffin-egg shape). Divide the dough into 9 pieces. Press each piece of dough flat on the palm of your hand, put some filling in the middle. Roll the dough over it, roll into a ball. Pour into the hollows and press down a little. Cover again and let rest for about 15 minutes. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes. Remove the eggs from the pan and let them cool down on a cake rack. Put icing sugar and egg white in a bowl and mix to a smooth glaze with the whisk of the hand mixer. If the icing is too firm, stir in a few more drops of water. Remove three tablespoons of the icing, divide the rest into thirds and colour with food colouring light blue, pink and yellow.
