Clean and peel potatoes. Cut into evenly sized cubes, about 1/2 inch in size. Thoroughly rinse potatoes to remove any excess starch. Add to medium sized pot or saucepan and add water until potatoes are covered in about 1-1 1/2 inches of water (approximately 5 cups of water) and add 1 tsp salt.
On medium-high heat, bring potatoes to a boil. Once boiling, reduce to a simmer and cook for 12-14 minutes, until potatoes are tender and a fork will easily pierce through the potatoes. While potatoes are cooking stir every 5 minutes or so to make sure they don't stick to the bottom of the pot.
Once potatoes are cooked through, drain and return to pot or to a medium sized mixing bowl. Add garlic cloves, milk, butter, salt, pepper, and Tabasco and mash well with a potato masher. Enjoy!
