Fiori di Sicilia Sponge Cake with Poured Custard



Fiori di Sicilia is an all natural Italian extract that is a cross between vanilla and citrus. It gives this light as air sponge cake a fabulous exotic twist that goes beautifully with summer berries. I love to serve this cake with a classic poured custard, an old school favorite of mine.

Poured Custard


This custard should be served ice cold and has the consistency of thin pancake batter. It is a nice change up from whipped cream or ice cream.


2 cups whole milk

4 egg yolks

¼ cup sugar

Pinch of salt

1 teaspoon vanilla extract



  • In a double boiler, place all of the ingredients except the vanilla and whisk until well incorporated

  • Bring the water to a simmer and slowly heat the custard

  • Sir the custard constantly until it begins to thicken, being careful not to let it boil. It will thicken as it cools

  • Beat the custard to release heat, add the vanilla, and then finish cooling in the refrigerator.





To serve pour custard in a shallow bowl or plate, place the cake on top and serve with berries
