First, give the potatoes a little scrub in cold water to remove any leftover dirt. Don't scrub too hard or you will remove all the skin.
Cover the potatoes with cold water and add the salt and garlic. Put a lid on and bring to a boil. Once boiled, turn down to a simmer and cook for about 10-15 minutes or until completely soft when poked with a knife.
Drain the potatoes and discard the garlic. Add the butter, black pepper and a few leaves of fresh mint. Mix gently with a spoon.
Serve in a big bowl or plate. Garnish with a nice sprinkling of crunchy Maldon sea salt and fresh sprigs of mint. Enjoy!
Always cook root vegetables with cold water first. This helps to keep their nice shape after cooking.
