Scrub, peel, and cut potatoes into one-inch cubes.

Place potato cubes into a large pot and cover with water.

Boil potatoes over medium-high heat for approximately 10 minutes (until firm-tender). Insert a fork in a potato cube to test doneness.

Drain cooked potatoes and set aside to cool.

Place the cooled potatoes in a large mixing bowl. Chop the onions and celery and add to potatoes.

Hard-boil eggs. Cool and peel eggs.

Place a cooling rack over the potato mixture bowl, push the eggs through the wire opening, or chop them and add them to the mixture.

Mix the mayonnaise, mustard, pickle relish, salt, and pepper in a separate bowl.

Fold the dressing into the potato mixture.

Garnish with paprika and sliced spring onions.
