Fill a medium saucepan with water and the white vinegar; bring to a very gentle simmer over medium-low heat.
Toast the sprouted grain English muffin half until golden brown and crisp.
In a small skillet, lightly sear the Canadian bacon over medium heat for 1-2 minutes per side until warmed through and slightly browned.
Prepare the hollandaise by whisking the egg yolk and lemon juice in a heat-proof glass bowl set over (but not touching) a pot of simmering water.
Whisk the yolk mixture vigorously until it doubles in volume and thickens slightly.
Slowly drizzle the melted ghee into the yolk mixture while whisking constantly to create a smooth, thick emulsion.
Remove the sauce from heat and stir in the sea salt and cayenne pepper; keep warm.
Carefully crack the whole eggs into the simmering vinegar water and poach for 3 minutes until the whites are set but the yolks remain runny.
Place the seared Canadian bacon on the toasted muffin, top with the poached eggs using a slotted spoon, and drizzle with the warm hollandaise.
Garnish with fresh chives and a crack of black pepper before serving immediately.
