Fill a medium or large skillet about halfway with water, mix in 2 tsp of white vinegar and 1 tsp sea salt and bring to a simmer. Crack an egg into a small ramekin, and holding the ramekin right over the simmering water, gently slide the egg into the pan. Cook the egg for two minutes or so, using a slotted spoon to gently keep the egg white as close to the yolk as possible, then when the white looks opaque, use the spoon to very gently turn the egg over in the water. Cook for another couple minutes or until white appears to be cooked through. Place poached egg on top of grits cake and bacon. Repeat poaching process with the rest of the eggs.
