Matthew's is a good retail brand of English muffin in the New York City area. No restaurant bothers to do this. Poached till whites are set, though not chewy. The yolk can range from runny to almost set, depending on personal preference. Excess white is sometimes trimmed before serving.
Canadian bacon comes from the meatier loin, along the backbone.
It is trimmed of excess fat and is cured like ham. Too often, standard ham is substituted in eggs Benedict. Canadian bacon should be freshly sliced and grilled for extra flavor and texture. A hardly cooked, gently thickened egg-yolk and butter sauce, usually with lemon juice but occasionally with vinegar. The lemon flavor should be prominent but not overwhelming.
