2 tbsp distilled white vinegar – for poaching water
8 large large eggs
4 pieces english muffins – split
Instructions
Set up a medium saucepan with 2–3 inches of water and bring it to a bare simmer over medium heat; reduce to low to maintain tiny bubbles.
Make the Hollandaise: In a small pan, heat 10 tbsp unsalted butter until fully melted and hot but not browned. In a heatproof bowl set over barely simmering water, whisk together the egg yolks, lemon juice, and warm water until thickened and the whisk leaves trails, 2–3 minutes. Slowly drizzle in the hot melted butter while whisking constantly until the sauce is glossy and pourable, 2–3 minutes. Whisk in 0.25 tsp kosher salt and the cayenne. Keep warm off heat; if it thickens, whisk in a few drops of warm water.
Poach the eggs: Add the distilled white vinegar to the simmering water. Crack the large eggs into small cups. Slide in 3–4 eggs at a time and poach at a bare simmer until the whites are set and the yolks are still soft, 3–4 minutes. Transfer to a paper towel–lined plate and repeat with remaining eggs.
