Place a small pot of water with one tablespoon white vinegar on high heat and bring to a boil
While waiting for water to boil, crack two eggs into a small dish being sure not to break yolks, set aside
If using avocado, slice or mash with a fork
Place English Muffins in toaster and toast to liking
When water is boiling, use one had to hold egg dish near pot and use the other hand to stir water briskly until a vortex forms (see video!) then gently, carefully pour eggs into center of vortex
Cook 2-5 minutes. I like my yolks runny so I cook 2 1/2 minutes.
Butter English Muffin, add two slices of Canadian bacon, avocado (if using), then add egg
Spoon Hollandaise Sauce over eggs and season with salt and pepper. Garnish with chives if desired.
