Bring a medium pot of water to a gentle simmer and add the white vinegar to help the egg whites congeal.
Crack each of the 2 eggs into a small ramekin, then carefully slide them into the simmering water to poach for 3 minutes until the whites are set but yolks remain runny.
In a small heat-proof bowl, whisk the single egg yolk and lemon juice over a pot of barely simmering water using the double boiler method until the mixture begins to thicken.
Slowly drizzle the melted ghee into the yolk mixture while whisking constantly until the sauce is thick, glossy, and emulsified.
Season the hollandaise with sea salt, black pepper, and a pinch of cayenne pepper, then remove from the heat immediately.
In a skillet over medium heat, lightly brown the Canadian bacon slices for 1-2 minutes per side until heated through.
Toast the sprouted English muffin half until golden and crisp to provide a sturdy base.
Place the Canadian bacon on the toasted muffin, top with the poached eggs, and generously spoon the warm hollandaise over the top before serving.
