Fluffy Mashed Potatoes

I found this recipe on recipezaar and have made it a few times now. It sounds more time consuming than it really is and don't be scared away by the eggs.

8 large potatoes, peeled and quartered
1 t. sea salt
pepper to taste
1/2 c. butter (I've used less and still have good results)
3/4 c. milk (use less milk if potatoes are small, maybe start with 1/2 c. and go from there)
1/2 c. sour cream
2 eggs

1 - In a large pan, boil potatoes until tender, 15-20 min.
2- Drain water, and add remaining ingredients.
3- Mash until smooth, with a potato masher. I've never before made mashed potatoes with a potato masher and was surprised at how fast it was. Don't use a mixer, they'll be gooey if you do.
