Revisiting September: Here’s a cake I made in september 2014, a blood orange upside down cake. This cake does blood oranges two ways – candied on the top of the cake, (which started off as the bottom) and whole oranges, skin and all, blitzed through the batter. A lovely introduction to the coming months of spring, when it will be warm enough to have afternoon tea in the garden!
2 + 2 blood oranges
200g + 200g sugar
125g very soft butter
2 free range eggs
½ tsp vanilla essence
200g plain flour
1 tsp baking powder
Candied Blood Oranges
Finely slice 2 of the oranges, discarding the ends and keeping as many slices intact as you can.
Dissolve 200g of the sugar in 1/2 cup of water in a saucepan, and bring to the boil. Carefully place the orange slices in the syrup and simmer them until they are soft and sticky. Remove from the syrup using tongs. If the syrup is not reduced enough, cook it for a few minutes extra to thicken – but don’t let it go to toffee.
Preheat oven to 170 degrees C.
Grease a 20cm springform cake tin. Line the base with baking paper, cut slightly larger than the circle base, making sure the paper comes a little way up the sides of the tin. This is as a precaution, in case the syrup leaks out of the tin.
Chop 2 of the blood oranges in quarters and remove each end. Blitz in the food processor until reasonably finely chopped – there should still be some small chunks in the mixture.
Add the butter and 200g of the sugar and blitz in the food processor. The mixture will look very curdled! Add the eggs and vanilla and blitz again, the mixture will still look very curdled!
Gently fold in the flour and baking powder, making sure not to over mix or the cake with toughen. The cake mixture will now look “normal”.
Place the candied orange slices on the paper base in the springform tin, as artistically as possible, remembering, as this is an upside down cake, that the bottom becomes the top.
Place the batter over the top of the slices. Gently tap the mixture to even it out. Bake for 30 minutes or until a skewer inserted in the centre comes out clean.
Remove from the oven and cool the tin on a wire rack. When the cake is cool (not cold), carefully turn upside down on a serving plate. Release the springform clasp, and carefully remove the ring. Even more carefully, take off the base and peel away the baking paper.
You should have a beautiful upside down cake with fruit intact! Brush the cake with the blood orange syrup, or you could serve the syrup on the side as a sauce.
Serve with whipped cream or sour cream or creme fraiche. I prefer the latter two as the cake is very sweet and needs to be offset by a little sourness.
