Here is my interpretation of the signature challenge from episode 3 of GBBO's 11th season: Irish soda bread. I thought of several different ways, with a few putting a twist on a classic whiskey highball that would use an Irish whiskey and club soda to directly capture the "Irish" and "Soda" parts of the name. Instead, I broadened my interpretation and used Guinness as the foundation to incorporate an Irish element with the beer's carbonation representing the soda. I opted for a dessert soda bread, so I used blood orange and chocolate flavors.
For the drink:
-5 oz Guinness Draught
-1/2 oz blood orange liqueur (Solerno)
-1/2 oz creme de cacao (Tempus Fugit Creme de Cacao)
Irish soda bread (I used the recipe from Paul Hollywood's Bread)
Pour the blood orange liqueur, creme de cacao, and cold Guinness into cocktail mixer. Don't add ice. Stir gently for 3-5 seconds to incorporate. Pour into your glass and enjoy.
