Step 1

Heat 3 inches water and vinegar in a wide, shallow saucepan or Dutch oven over medium high heat. Bring to a boil; reduce heat and simmer.

Step 2

Crack each egg into a separate bowl or small ramekin. Working carefully, gently slide each egg into the saucepan.

Step 3

Cook, undisturbed, until whites are cooked through, about 3-5 minutes. Using a slotted spoon, carefully remove eggs and transfer to a paper towel-lined plate.

Step 4

Heat a large skillet over medium high heat. Working in batches, cook ham until lightly browned and heated through, about 1-2 minutes per side.

Step 5

Place English muffins open-faced on a platter. Top evenly with ham and eggs, drizzling the tops with hollandaise sauce, garnished with chives and dill, if desired.

Step 6

Serve immediately.

Step 7

Combine egg yolks, lemon juice, salt and cayenne pepper in a blender until pale yellow in color, about 30-60 seconds. With the motor running, add butter in a slow stream until emulsified; season with salt and pepper, to taste.
