When I was in high school, one of my favorite ice cream flavors was mocha almond fudge because it was like a portable coffee and chocolate sundae, with the fudge and nuts neatly packed inside. For some reason I have never really considered making it, perhaps because I was unsure of how to marble the fudge with the ice cream. Last June, Kieran from Ice Cream Ireland put out a call for readers to try out some of his recipes in anticipation of his new book (still not readily available in the US, but you can order it from the publisher if you are eager like me—will let you know when it arrives) and I decided to try making his Kahlúa Espresso Ice Cream (my post about it here). The coffee flavor of this ice cream was amazing, and I knew right away I had to adapt it to make some mocha almond fudge ice cream. Nearly a year later, here it is.
I knew I already had the perfect fudge sauce recipe for this ice cream, but I needed to reduce the hot fudge sauce recipe by about half to provide just the right amount for this ice cream. Of course, I ended making a regular batch of hot fudge sauce later that night since my daughter loves it and was disappointed to learn there wasn’t any leftover after the smaller batch I made for this ice cream. While I was waiting for the ice cream to freeze in my ice cream maker, I thought about how hard the fudge sauce might get when once it was frozen. The original hot fudge sauce recipe is intended to be heated and poured over the ice cream, resulting in a thick, warm sauce. I decided to get a preview of what I might end up with and placed some sauce on a spoon and left it in the freezer. After 10 minutes, I knew that it would be too hard once frozen with the ice cream. I salvaged the first batch of fudge sauce by adding a little more evaporated milk and stirring it in to the still warm sauce, resulting in just the right texture once frozen.
The first time I made this I added the almonds and the fudge to the ice cream maker immediately before shutting it off, but the fudge ended up getting too blended. In addition, the almonds generally sank to the bottom of the ice cream as it ripened in the freezer. To remedy both problems, I decided to let the ice cream firm up in the freezer for an hour before layering in the almonds and room temperature fudge sauce. A few plunges of the spatula into the ice cream broke up the layers and gave the fudge marbling a more random appearance, while still preserving the yummy chocolate veins.
There are a lot of steps to this recipe, but you can take advantage of the chill time of the ice cream base, the initial freezing of the ice cream, or the hour of firming up in the freezer before layering the almonds and fudge sauce. I’ve arranged the steps in the recipe to take the least amount of time possible, but you could toast the almonds or make the fudge sauce ahead of time. If the sauce is chilled, you will want to get it to room temperature so that it will be easier to distribute in the ice cream layers. Once the ice cream is finally ready to eat, you will understand that your efforts were worth it and why I didn’t think twice about making this a second time to refine the steps for this recipe. The Kahlúa, although not necessary if you have issues with alcohol, adds a wonderful depth to the coffee flavor in this ice cream. You will be thinking about your next batch as you finish the first.
Return custard mixture to saucepan and cook over medium heat, stirring frequently, until it reaches about 165° F.
Boil fudge sauce for 5 minutes and then remove from heat. Stir in 2 tablespoons + 2 teaspoons butter and 1/2 teaspoon vanilla and let cool to room temperature.
While ice cream is churning, chop about 2/3 cup of almonds. Use a colander to help remove the smaller, dustier particles.
Once ice cream has finished churning, transfer to a dedicated, odor-free container and let ripen in freezer for one hour.
Remove ice cream from freezer and begin layering another container with a layer of ice cream and then a scoop of room temperature fudge sauce.
