Halve any large potatoes and place in a large saucepan with larger pieces at the bottom. Cover with boiling water, add a pinch of salt and a couple of mint leaves and simmer gently for about 20 minutes.
Test to see if they are ready by pricking with a skewer – they should ‘give’ but not be falling apart. The cooking time will vary depending on the size of the potatoes, so check them after 15 minutes.
While potatoes are simmering, combine butter and chopped herbs.
Drain the potatoes and return to the pan over the heat for 30 seconds, shaking the pan gently to dry them.
Add the herb butter and swirl or toss the potatoes so they are well coated. Season with salt and pepper and serve in a warmed serving dish.
