Preparation
Spray the stoneware insert with cooking spray, then combine the milk, rice, and sugar. Stir well and cook on low for 4-6 hours, or high for about 4.
When the rice is tender, mix in a large mixing bowl, the eggs, cream, vanilla, cinnamon, and salt.
Scoop a 1/2 cup of the hot rice mixture into the mixing bowl and whisk.
Keep adding 1/2 cup at a time of the rice and milk mixture into the egg bowl until about half of the milk and rice mixture is gone from the slow cooker.
Then pour everything back into the pot.
Stir well.
This is called "tempering your eggs"---you have to do this step, or your eggs will scramble on you when you add them to the crock.
Cover and cook on high for 1 hour.
Stir well, then take the lid off of the cooker and unplug it.
When the rice pudding is room temperature, you can refrigerate it.
