Prepare the toutons and lightly fry the ham.
Hold toutons and ham in a warm oven while you poach the eggs and make the hollandaise sauce
In a blender, combine the egg yolks, mustard and lemon juice for only a few seconds.
With the blender on medium speed, slowly pour in the hot butter in a thin stream; the sauce should thicken quite quickly.
Pour sauce into a bowl and keep warm in a warm water bath while preparing the other components of the Newfoundland Toutons Benedict.
Place the cooked ham on the warm toutons, top with a poached egg and finally the hollandaise sauce.
