Crack the eggs into the Ninja Foodi inner pot, add the sugar and half & half. Turn the Ninja Foodi on low sear/sautè.
Use a Silicone Whisk to whisk up the eggs and half & half. If you don't have a silicone whisk, whip up the eggs before you add them them to the inner pot.
Allow the pot to heat the mixture to 150°F/66°C. This usually takes about 25 minutes and you want to whisk or stir frequently to prevent any of the egg mixture to cook on the bottom.
If your mixture is not coming up to 150°F/66°C by the 20 minute mark, increase the heat to low-medium and stir constantly. Bring the temp up to 150-155°F/66-68°F and then take the temperature down to low again and hold the temp at 150°F/66°F for 5 minutes. If your mixture starts to get higher than 160°F/71°F, remove the inner pot so the temp doesn't get any higher and set the eggs. Stir constantly.
Add the spices, vanilla extract, and heavy whipping cream. Whisk to combine. Chill for at least 4 hours. Serve and Enjoy.
If you want to add liquor to the eggnog, add it after the cooking process. I really recommend trying a pecan whiskey or bourbon in the eggnog, it's delicious! Details of brands I recommend are in the written post.
