Blood Orange Olive Oil Cake

1. Preheat oven to 350°F. Grease a 9 by 5 inch loaf pan with unsalted butter. I actually had a little trouble getting my cake out of the pan, so you might want to also flour the pan or line with parchment paper.
2. Place sugar in a large bowl. Grate zest from 2 blood oranges into the bowl with sugar. Using your fingers, rub the the zest and sugar together until evenly distributed.
3. Next, supreme (segment) 5 of the blood oranges (2 for the cake, 3 for the compote) into two piles. To supreme a blood orange, cut off the top and bottom just until the pulp is exposed. Stand the blood orange up on one of the flat ends. Working from top to bottom, cut away the the peel and pith, following the curve of the fruit. Slice out each orange segment by cutting in towards the center of the fruit along the connective membranes. The segment should fall out on its own, but you can use your knife to help if needed. Repeat with remaining 4 oranges.
4. Place the larger pile of segments (from 3 oranges) in a small bowl and set aside for the compote. Roughly chop the remaining segments and set aside for the cake.
5. Halve the remaining blood orange and squeeze juice into a measuring cup (about 1/4 cup). Add buttermilk to the measuring cup until you reach the 2/3 cup mark. Pour juice-buttermilk mixture into the bowl with sugar and zest and whisk until combined. Whisk in eggs.
6. In a different bowl, combine flour, baking powder, baking soda and salt, whisking to combine. Add dry ingredients to wet ingredients and gently whisk until combined. Switch from whisk to spatula and fold in extra virgin olive oil in several additions (4 to 5 additions is fine). Fold in roughly chopped orange pieces. Pour batter into prepared pan and smooth the top.
7. Bake for 50 - 55 minutes or until the cake is golden brown and a skewer (or knife) inserted into the center comes out clean. Let cool on a rack for 5 minutes. Carefully unmold the cake and let cool to room temperature.
8. While the cake is cooling, prepare the honey-blood orange compote. Drizzle 1 to 2 teaspoons of honey over prepared blood orange segments (from paragraph 3 above). Let sit for 5 minutes, then stir gently.

To serve, place a slice of cake on a small plate. Spoon honey-blood orange compote over the cake and finish with a dollop of whipped cream.
