Set a pot of water to boil for the eggs.
Split the English muffins and toast them. Set aside, keeping warm if possible.
If using Canadian bacon, cook it in skillet or under broiler, or warm if using ham.
Make or warm your Hollandaise sauce. For easy blender sauce, put the yolks, cayenne, mustard and lemon juice in a blender container and blend until smooth. Melt the butter and pour into the yolk mixture with the blender running so that it combines smoothly. Set aside.
Lastly, poach the eggs. Add the vinegar to the boiling water, then carefully crack the eggs in to the simmering water. Cook for around 3-4 minutes until the whites are translucent but the yolks are still slightly soft. Remove with a slotted spoon.
Assemble the eggs Benedict - make stacks with half a muffin at the bottom, topped with bacon/ham, then a poached egg and topped with the Hollandaise sauce.
