Place 1 cup of water in the Instant Pot and insert a steamer basket. Place in 4 eggs and turn on to high for 5 minutes. Once timer goes off, let sit for 5 minutes and then manually release the pressure. Place eggs in a bath of ice water for 10 minutes. Peel and set aside.
While eggs are cooking preheat the oven to 400. Mix together warm water, cream of tartar and baking soda.
Mix together all remaining ingredients, including cream of tartar water. Place in fridge until eggs are done.
Split sausage mixture into 4 even portions. Cover each egg with an even portion of sausage. Place on a baking sheet and refrigerate for 10 minutes. Bake for 15-20 minutes.
Notes
You can make this entire recipe in the Instant Pot! After coving the eggs in the sausage, heat some oil in the Instant Pot over Saute. Brown all sides of the eggs, around 6 minutes total. Remove and place one cup of water into the inner pot with a rack. Place the eggs inside and pressure cook on high for 8 minutes. Once time is done use quick release to release the remaining pressure.
