Grill the bacon to your like and keep it warm.
Half each muffin ready for toasting.
Boil the kettle for poaching the eggs.
In a measuring jug or the container that comes with your stick blender, add the lemon juice, water and salt, and set aside.
Melt the butter slowly in a small saucepan and keep warm.
Put boiling water in a medium saucepan and bring to a gentle simmer, then add the vinegar.
Crack each egg for poaching into a cup and place individually into the simmering water to poach for 2 to 3 minutes (depending on the size of eggs used) - you can do this one at a time or all at once. If poaching the eggs separately, once cooked, put them in a bowl of iced water to stop the cooking process and they can be placed back in the hot water to warm through at the end.
While the eggs are poaching, toast the muffins.
Now you're ready to assemble - butter the muffins, top each half with 2 slices of bacon, and then top each half with a softly poached egg.
