The ice cream has a few extra steps but is well worth making. Bettie and I thought the plums cooked to swirl in the ice cream were good enough to eat as a pour on sauce for cake, ice cream and maybe on toast if cooked down a little more.
I got impatient and did not wait long enough for my plum sauce to freeze well so mine isn’t as pretty as the recipe photo, but it sure tastes good. I added about a teaspoon of Amaretto to the ice cream for the flavor and to keep it from freezing so hard. Also added a teaspoon of vanilla which is not in the original recipe.
I really think this would work well with any stone fruit, but the plums are tangy and really make a great ice cream and look so good.
Buttermilk Plum Swirl Ice Cream
2 cups half-and-half
1 cup buttermilk
1 cup heavy cream
6 large egg yolks
1 1/3 cups sugar
1 teaspoon vanilla
2 cups peeled, chopped black plums

Place bowl containing custard mixture in ice water, and cool completely (about 30 minutes), whisking occasionally. Cover and chill custard mixture 2 hours.
Meanwhile, stir together plums, corn syrup, salt, and remaining 3 Tbsp. sugar in a small saucepan, and cook over medium heat, stirring occasionally, 12 minutes or until plums are very tender. Remove from heat; let stand 15 minutes. Stir in lemon juice. Cover and chill plum mixture 2 hours.
Pour custard mixture into freezer container of a 2-qt. electric ice-cream maker, and freeze according to manufacturer's instructions. (Instructions and times may vary.) Transfer ice cream to a freezer-safe bowl or pan, and freeze 1 hour. Meanwhile, freeze plum mixture 30 minutes. Dollop frozen plum mixture over frozen ice cream, and gently swirl.
