Chocolate Citrus Cake by Angel Castillo

(This recipe appeared in the Summer 2022 issue of Pastry Arts Magazine)

The Chocolate Citrus Cake was inspired by the seasonal citrus from Austin, Texas. I use oranges from local farmers that are ripe and sweet, and pair them with a dark chocolate so that the orange flavor stands out. I also wanted to add a touch of savory, which is where the hickory smoked sea salt comes into play.
