Boil potatoes: Place potatoes in a large pot of cold tap water with 1 tbsp salt. Bring to a boil over high heat, then lower heat to medium so they're simmering gently (this stops skin splitting). Cook for 10 - 15 minutes until there's no resistance when pierced with a knife. Alternatively, steam the potatoes.

Steam dry: Drain in colander then leave for a minute to let the potatoes steam dry (if wet, butter won't stick).

Toss with butter: Transfer to a bowl, add salt, pepper and butter. Toss to melt and coat.

Add herbs just before serving. Stir through, transfer to serving bowl and serve warm!
