Preheat waffle iron. If your waffle iron has controls, then preheat on medium. Shred the potato, then place in either a dish towel or paper towels and squeeze all of the moisture out of the potatoes.

Melt the butter in a medium sized bowl in the microwave (or in a small sauce pan on the stovetop). Mix the butter, potatoes, sea salt and pepper together until the potatoes are all coated in butter. Spread the potatoes onto your preheated waffle iron and close the lid. Press down gently to help compress them together. Let cook until golden brown. You can check on them after they have been cooking for a few minutes to gauge their progress. Top with chopped chives and serve.
