Avoid blenders or processors — they overwork the starch and make the mash gluey.
Add the Butter
Stir in butter cubes immediately so they melt into the hot potatoes.
Pour in the Hot Cream
Warm cream (don’t boil).
Add slowly in a thin stream, stirring until silky and smooth.
Season & Finish
Taste, adjust salt, and add pepper if desired.
Sprinkle chopped chives for a fresh touch.
