Courgettes in cake sounds odd, but it's an American classic. Spiced with nutmeg, the cake is moist, delicious and easy.
Preheat the oven to 180C/350F/Gas 4.
Place the eggs into a food processor and blend. Add the oil, sugar and vanilla extract and blend again, until thick and foamy. Stir in the grated courgettes and the pineapple pulp.
In a separate bowl, mix together the flour, bicarbonate of soda, salt, baking powder, cinnamon and nutmeg. Add the dry ingredients to the wet ingredients a third at a time, gently folding with a rubber spatula after each addition. Add the walnuts and raisins and stir.
Grease two 12.5cm x 20cm/5in x 8in loaf tins and dust with flour. Divide the batter equally between the tins.
Transfer to the oven and bake for about an hour, or until a skewer inserted into the centre comes out clean. Cool in the tins for ten minutes, then turn out onto wire racks to cool completely before serving.
