Next to yogurt cakes, I’m a big fan of any cakes that use olive oil and show it with pride right in the recipe name. Despite the kind of citrus used in this recipe, the cake actually has more of a lemony flavour than grapefruit, as my brother described it; he was my first taster and loves this cake.
The original recipe, which I found on Smitten Kitchen, uses the grapefruit segments in the cake. I used a small amount of the grapefruit segments, cut up, into some of the batter and baked a test batch in a little cupcake liner. While I loved the extra fruit in the cake it left a bitter aftertaste that I wasn’t fond of, which I did not get when I ate the grapefruit raw. I’ve read about citrus becoming bitter after baking, even with copious amounts of sugar, but had never experienced it in my own baking until then. Oh well, it did look pretty.
