Method
1. Whisk the eggs with the sugar until thick, then whisk in the oil and crème fraîche.
2. Sieve the flour, baking powder, bicarbonate of soda, salt and mixed spice, then mix in orange rind and chopped hazelnuts. Fold the flour mixture into the eggs with the grated courgettes. Pour the mixture into a cake tin.
3. Place the tin on the grid shelf set on the floor of the baking oven. Bake for about 45-50 minutes until golden and cooked.
If your AGA does not have a baking oven, place the tin on the grid shelf set on the floor of the roasting oven and slide the cold plain shelf on the second set of runners down. Bake for about 45-50 minutes until golden and cooked. Change the cold plain shelf for a large roasting tin after 30 minutes.
Rayburn and Conventional Cooking: Bake at 180ºC, fan oven 160º, for about 45-50 minutes, until risen, golden and cooked through.
4. To make the icing; melt the butter in a bowl on the AGA. Add the remaining ingredients to the butter, beat together well and spread on the cake. The icing will thicken on cooling. Mark a pattern with a palette knife. Allow the icing to set.
