Blood orange upside down cake

I made this cake in an attempt to make the most of the blood oranges that are in season. I have followed a recipe from Feedfeed but simplified it to suit me.

I will write down how I made it as I know I will want to make this again for my friends who have celiac disease.

Ingredients

4 medium blood oranges

½ teaspoon fine sea salt

1½ teaspoon baking powder

½ teaspoon baking soda

120 ml extra virgin olive oil
