Fill a large bowl with ice water and set it aside.
In a small saucepan, whisk together the egg yolks and sugar
until the mixture is smooth and the sugar is dissolved. Do not do this over
heat.
Whisk in the milk, heavy cream, cream cheese, vanilla, and
strawberry jam.
Place the pan over medium heat. Cook, stirring constantly with a rubber spatula, until the temperature reaches 74°C to 80°C on an instant-read thermometer.
Remove the pan from the heat and pour the base through a
fine-mesh strainer into a clean CREAMi Pint. Carefully place the container in
the prepared ice water bath, making sure the water doesn't spill into the base.
Once the base has cooled, place the storage lid on the pint
and freeze for 24 hours.
Remove the pint from the freezer and take off the lid. Place
the pint in the outer bowl of your Ninja CREAMi, install the Creamerizer Paddle in the outer bowl lid,
and lock the lid assembly onto the outer bowl. Place the bowl assembly on the
motor base, and twist the handle to
the right to raise the platform and lock it in place. Select the Gelato
function.
Once the machine has finished processing, remove the lid
from the pint container. With a spoon, create a 11/2-inch-wide hole that
reaches the bottom of the pint. During this process, it is okay if your treat
reaches above the Max Fill line. Add the graham cracker pieces to the hole in
the pint, replace the lid, and select the Mix-In function.
Once the machine has finished processing, remove the gelato
from the pint. Serve immediately.
