Boil the chopped floury potatoes in cold water with a pinch of salt. Bring to a boil, then simmer for about 15 minutes until fork-tender.

Drain the potatoes and return them to the saucepan to keep warm.

Add the grated cheddar cheese and salted butter to the warm potatoes, seasoning with salt and pepper.

Mash the potatoes with cheese and butter until desired consistency, adding milk or cream for creaminess if desired.

Serve warm, garnished with fresh herbs if desired.
