Prepare Potatoes
Peel and cut potatoes into even chunks (about 2 inches).
Place in a large pot and cover with cold water. Add 1 tablespoon of salt.
Boil
Bring to a boil over medium-high heat.
Reduce heat and simmer for 15–20 minutes, or until potatoes are fork-tender.
Drain & Dry
Drain potatoes well and return them to the pot.
Allow them to sit over low heat for 1–2 minutes to evaporate excess moisture.
Mash
Use a potato masher, potato ricer, or hand mixer to mash the potatoes until mostly smooth.
Add Butter & Cream
Add the butter pieces and mash until melted.
Slowly pour in the warm cream, mixing until creamy and fluffy.
Season
Stir in salt and pepper. Adjust seasoning to taste.
Serve
Transfer to a serving bowl and top with a pat of butter or chopped fresh herbs if desired.
