Instructions

Grapefruit Curd

In the bowl of a stand mixer, beat the butter and sugar for 2 minutes. Slowly add the eggs and yolks and beat for 1 min. Add the grapefruit juice (mixture will look curdled.)
In a medium saucepan, cook the mixture over low heat until it's appearance smooths out. Increase the temperature to medium and cook, stirring constantly for about 15 minutes (until the mixture thickens.) Don't let the mixture boil.
Remove the saucepan from the heat and stir in the grapefruit zest. Transfer the curd to a bowl and press plastic wrap on the surface of the grapefruit curd. Chill in the refrigerator and it will thicken as it cools.

Grapefruit Buttercream Frosting

Beat the butter and grapefruit zest at medium speed with an electric mixer until creamy (1-2 minutes.) Gradually add the powdered sugar, alternating with grapefruit juice, beating at low speed until blended.
