Pour the cream cheese, sugar, vanilla bean paste, lime curd, half and half, milk, and lime juice into a small blender and blend until all ingredients are fully combined. Pour the mixture into a Ninja Creami pint container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
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 hole in the center of the ice cream and add the graham crackers and lime zest.
Put the pint back into the Ninja Creami and process on the "Mix-Ins" function. Once the Ninja Creami is finished processing, remove from the machine.
Your ice cream is ready to eat! Enjoy!

Notes
Can homemade lime curd be used instead of jarred?Yes, you can use homemade lime curd for this recipe. Lime curd is made of lime juice, white sugar, eggs, salt, and butter. It's really quite easy to make. Here's a recipe for making homemade lime curd.What's the difference between key limes and regular limes?Key limes are much smaller, rounder, and yellower when ripe in comparison to regular limes. The flavor of key limes is similar to that of regular limes as they are both quite tart. But, key limes are not quite as sour as regular limes. In recipes like my Ninja Creami Key Lime Gelato, a very small amount of the actual lime juice is used so the flavor difference will not be noticeable.
