These Grand Marnier basil watermelon bars are perfect for the season. I have never seen a recipe like this before. The sorbet and the cream in a frozen bar. These are great because you can add alcohol, or not. Whatever you prefer. Thanks to 17 and baking for the unique and refreshing recipe.
Frozen Grand Marnier Watermelon Basil-Lime Bars
1 1/2 pounds (24 oz) seedless watermelon, rinds removed
1/2 cup sugar
1 tablespoon Grand Marnier (or tequila, rum, etc) (optional)
Juice of a small lemon
One (14 oz) can sweetened condensed milk
3 tablespoons finely chopped fresh basil
Zest of a small lime
Juice of two small limes
1/2 cup heavy whipping cream, chilled
Line the bottom and sides of a 9”x9” pan with plastic wrap so that there is some overhang on all four sides. (I used aluminum foil, but I wouldn’t recommend it. It flaked later on when I cut the bars.) Place the lined pan in the freezer while making the watermelon sorbet.
To make the sorbet, blend the watermelon in a blender or food processor until smooth. Add the sugar, Grand Marnier, and lemon juice and blend until very smooth. Chill the mixture in the freezer for 30 minutes or until very cold, then churn in an ice cream maker. Spread the churned sorbet in the prepared pan and freeze at least 2 hours, or until the sorbet has hardened.
To make the semifreddo, heat the sweetened condensed milk with the basil in a small saucepan over medium heat until it steams. Remove from heat and let cool to room temperature. When cool, whisk in the zest and lime juice until smooth. In another bowl, whisk the whipping cream until it just reaches stiff peaks. Fold it into the sweetened condensed milk gently with a rubber spatula.
Smooth over the watermelon sorbet in the 9”x9” pan and freeze until solid, preferably overnight. I also recommend putting plates in the freezer at this point so when you’re ready to serve the bars, you can use chilled plates and the bars won’t melt as quickly.
When ready to serve, use the overhanging plastic wrap to lift out the bars. Cut into squares and serve on chilled plates.
