375g / 13oz unsalted butter
300g / 10½oz dark muscovado sugar
150g / 5½oz golden syrup
900g / 2lb plain flour
1 tbsp bicarbonate of soda
2 tbsp ground ginger
FOR THE ROYAL ICING
3 free-range egg whites
675g / 1½lb icing sugar, sifted
3 tsp lemon juice
FOR THE 'ENAMEL' ICING
400g / 14oz icing sugar
3-4 tbsp water
2-3 drops food colourings
- To make in an AGA City60 set the top oven to Baking temperature. For other AGA cookers, the Baking Oven or in the Roasting Oven and reduce the suggested baking time by half.
- Melt together the butter, sugar and syrup. Sieve the flour, bicarbonate of soda and ground ginger into a large bowl and make a well. Pour in the melted butter mixture, stir and knead into a stiff dough when cool.
- Using your own templates, cut out the sections for the lid/top plate, sides, rectangles for oven doors and circle for the top plate. Slide onto baking trays or cold plain shelves lined with baking parchment or Bake-O-Glide.
- Bake for about 12 minutes. Trim the shapes if the mixture has spread with a sharp knife whilst the biscuit is still warm, using your templates as a guide. Leave to cool completely.
- For the 'enamel' icing, sift the icing sugar into a large bowl and stir in enough water to create a smooth mixture. Stir in the food colouring.
- Carefully spread the icing onto the biscuits using a pallet knife and set aside until the icing completely hardens. At this stage you can add any additional decorative features such as silver candy balls on the top plate as we have.
- For the royal icing, whisk the egg whites in a large bowl until frothy. Using a wooden spoon or a hand-held electric mixer on slow speed, add the icing sugar a tablespoonful at a time. Stir in the lemon juice and beat the icing until it is very stiff and white and stands up in peaks.
- Spoon a little of the icing into a piping bag fitted with a medium plain nozzle. Pipe some icing along the side pieces edges and join the AGA together on a cake board. Leave the icing to dry and harden for a minimum of four hours, but preferably overnight. You can repeat this with various colours to create a desired effect on your AGA such as the black icing around the base for a plinth and the addition of a rail on the front studded with more silver balls for a chrome effect.
