Blood Orange Polenta Olive Oil Cake & Orange Mascarpone Icing
Winter is the premier, peak growing season for citrus. Luscious lemons, tangy limes, and fragrant oranges. Southern Italy is known for blood oranges, considered by many to be some of the world’s finest dessert oranges. These oranges can be recognized from other oranges by first glance at their skin’s red-blushed color. Once opened, they surprise you by their burgundy, blood-red, ruby-colored fruit that taste a bit tart and berry-like. Blood oranges spoil easily, so they need to be kept cool in the refrigerator for a week at the most.
To celebrate this season of citrus, I created and baked a special cake in which the star ingredients that stand out are blood oranges and their juice, olive oil, polenta (cornmeal), honey, and marscarpone cheese . . . all true to Italian cuisine. While the cake baked and just after taking it out of the oven, my house had a delicate aroma of oranges and orange blossoms. And during February, that scent is so fresh and welcome!
This cake has a more course, heavier crumb cake texture from the polenta (cornmeal), which is better for the orange syrup drizzled inside. It is dense, yet moist and possesses a less sweet taste that Italians prefer. The entire cake is balanced from the bright orange boost of flavor within. So those of in the States might prefer this cake with a sweeter after-dinner liquor or at mid-morning with a sweet cup of tea or coffee. This cake tastes even better after it sits for a day/evening.
