Hollandaise sauce : Mix the egg yolks, water, lemon juice, salt and pepper in a pan.
Put the pan on low heat and add the butter cut in small pieces gradually. When the sauce thickens, remove the pan from heat and set aside.
Poached eggs : In a pan with boiling water, add some white vinegar and use a spoon to form a swirl. Break your eggs in the water and cook for 3 minutes. Transfer the eggs in cold water when they're cooked.
Cook the bacon in a pan and toast your English muffins cut in half.
Make your sandwich : * an English muffin slice * a tablespoon Hollandaise sauce * a bacon slice * a poached egg * some Hollandaise sauce again * chopped chives * an English muffin slice on top
