Split the English muffins and toast to your liking. (Lightly toasted, gently crisp on the outside and tender inside if you're looking for a recommendation.) Divide among 4 plates.
Butter each muffin half while still hot and drape a slice of smoked salmon on top.
To poach the eggs, fill a wide sauté pan halfway with water. (A pan like this is ideal.) Add vinegar and bring water to a brisk simmer, then reduce heat so the water is virtually still.
Crack each egg into a small bowl and tip carefully into the water, submerging the bowl a bit as you pour. I like to add the eggs in a clockwise circle starting near the handle so I remember in which order to remove them for even cooking.
Cook undisturbed for four minutes, until whites are set and yolks are runny.
Remove eggs from pan with a strainer spoon (something like this). Gently place eggs on a paper towel-lined plate and dab the tops to remove excess water. Cut away any scraggly whites if you like.
To serve, place a poached egg over each English muffin half and spoon some Hollandaise sauce overtop.
Garnish with plenty of snipped chives and freshly ground black pepper. Serve right away
Notes
You can use your favorite variety of smoked salmon or gravlax — whatever makes you happy. The vibrant variety pictured here is smoked wild sockeye.
A couple of tablespoons of distilled white vinegar in the poaching water help the proteins in the egg whites to set beautifully while the yolks stay soft.
You can use any eggs you like, but sourcing good ones makes all the difference in such a simple recipe. Nothing beats the gorgeous golden yolk of a fresh egg from a well-treated hen. I've devoted a whole section to helping you parse the details.
Immersion blender Hollandaise sauce takes the guesswork out of the process. You'll never turn back — I promise.
This recipe is quick to make and at its best right off the stovetop, so I don't recommend making it in advance. That said, you may be surprised to learn that you can make poached eggs a day in advance, store them submerged in cold water in the fridge and simply reheat in a pan of barely simmering water for about a minute right before serving. Restaurants sometimes use this technique, and if you're cooking for a large crowd, it's a good one to keep in your back pocket.Hollandaise will keep in an airtight container in the fridge for 24 hours. Reheat gently so the sauce doesn't break.
