A few years ago, we took a vacation in southern Mexico, where I had an amazing slice of orange cake at a little cafe one day.
Came back, started searching for a recipe and discovered olive oil cake (a really good match) that has become "that really good cake Phil makes from time to time."
More recently, I've made a lemon version (lemon zest and juice in place of orange; limoncello instead of Grand Marnier) which the family all like even more.
Made one for today's breakfast. Thanks past-Phil!
