In a small saucepan, combine the heavy cream, milk, corn syrup, and sugar. Cook on medium heat while whisking continuously. Do not let the milk mixture burn. Cook until the mixture starts to look a little frothy. Do not boil the mixture.
In a separate bowl, whisk the eggs.
Temper the eggs by slowly pouring small amounts of the hot milk mixture into the eggs. Pour a couple of tablespoons at a time and whisk continuously.
Once all of the milk mixture has been added to the eggs, pour the milk and egg mixture back into the saucepan and cook on low heat for about 5 minutes or until it reaches 165 Degrees Fahrenheit. The mixture should start to thicken slightly, just enough to coat the back of a spoon. Remove from the heat.
Add the almond extract and stir.
Allow the ice cream base to cool before freezing.
Pour into an empty Ninja Creami pint container and freeze for 24 hours.
Process the Ice Cream
After 24 hours, remove the pint container from the freezer.
Place the pint container into the outer bowl of the Ninja Creami and then process on "Gelato."
Dig a well down the center of the ice cream, pour in the cherries, and process on mix-ins.
Remove the pint from the machine and enjoy!
Notes
What type of cherries should I use?Frozen, black cherries were used in this recipe. You can use fresh or frozen cherries. Jarred maraschino cherries could also be used if that’s all you have on hand, but they are much sweeter and taste more like sugar than fresh or frozen cherries.How long can I freeze my gelato?It depends. If you are keeping the ice cream in the Ninja pint container with the lid sealed tightly and are freezing it in a cold freezer (between 9 degrees F and -7 degrees F), your ice cream will keep for several weeks, even months. However, if you transfer your ice cream to another container or freeze it in a freezer that is not quite as cold (or that is accessed a lot/door opened and closed often), the lifetime of your ice cream will decrease greatly to just a few days and you will likely end up with freezer-burned ice cream.
