Fill a medium saucepan with water and the apple cider vinegar, bringing it to a very gentle simmer.
Crack each of the two large eggs into separate small ramekins to ensure the yolks remain intact.
Create a gentle whirlpool in the simmering water with a spoon and carefully drop the eggs into the center, poaching for 3 minutes until the whites are set but the yolks remain liquid.
While the eggs poach, whisk the single egg yolk and lemon juice in a small heat-proof bowl until the mixture doubles in volume.
Place the bowl over a pot of barely simmering water (double boiler method) and slowly drizzle in the melted ghee while whisking constantly until the sauce is thick and creamy.
Remove the hollandaise from the heat and stir in the sea salt, black pepper, and cayenne pepper.
Split the sprouted grain English muffin and toast until the edges are golden and crisp.
In a small skillet over medium-high heat, sear the Canadian bacon for 1 minute per side until warmed through and slightly browned.
Place the toasted muffin halves on a plate, top each with two slices of Canadian bacon and one poached egg.
Generously spoon the warm hollandaise sauce over the eggs and serve immediately.
