Cut potatoes into halves or quarter sections (but not too small).
Place potatoes in pot on stovetop and cover with water (two inches over potatoes). Add 1 Tbsp of salt. Bring to a boil.
Reduce heat and simmer until potatoes are fork-tender.
Drain water and mash potatoes thoroughly using a potato masher.
Fold in garlic and oil mixture, sour cream, pepper, and remaining salt. Enjoy!
