Preheat the oven to 350 degrees Fahrenheit.
In a medium pan on the stove, fry the 6 strips thick cut bacon until they cook through and are crispy. Once done, remove the bacon from the pan and place in a small bowl. Separately, remove the majority of the bacon grease from the pan and place it in another bowl. Leave a tablespoon or so of bacon grease in the pan.
Add the 1 medium white onion to the remaining bacon grease and continue cooking until the onions are soft.
Pour the bacon grease into the bottom of a large mixing bowl and then sprinkle in 1 500 mg Vitamin C supplement, crushed to a powder (only if grating the potatoes by hand) and mix to combine. This combination will keep the potatoes from browning as you prepare them.
Using the smallest side of a box grater or a handheld parmesan cheese grater/zester, grind 2 ½ lb Potatoes into a pulp. You are not making hashbrowns, but rather a juicy potato pulp. Periodically as you are grating the potatoes, put the pulp in the bowl with the bacon grease/vitamin c and mix to fully coat the potatoes in the substance. I would transfer and stir 5-6 times per potato to preserve the color of the dish!
Add the 2 eggs into the potato mixture along with 1 tsp Salt and ½ tsp black pepper and whisk to combine. Then dump the rest of the bacon, onions, and any remaining grease into the potatoes.
Pour the ingredients into a greased 9x9 glass pan. Top with the 8 Tbsp cold butter.
Bake in the oven for 70-80 minutes or until the top turns brown. You can do the toothpick test to make sure that it is cooked in the middle.
Cut into slices and serve topped with Sour cream and dill!
