Place the halved baby potatoes in a large pot and fill with cold water. Stir in 2 tsp salt, then bring to a boil. Once boiling, cook the potatoes until fork tender (typically 10-15 minutes depending on size, so just be vigilant).
Drain the potatoes in a colander and leave to sit as you prepare the butter. This is important to allow the steam to escape the potatoes.
In a large pan, melt in the butter over medium heat. As it begins to foam, keep gently stirring as the butter turns from a lemony yellow to a light brown colour. After a few more minutes you will start to see tiny dark specks start to form on the surface, these are just the milk solids. Once you see the butter turning a deeper brown colour, it will release a nutty aroma. This is when your butter is properly browned. If at any point the nutty aroma smells more like burning, then simple reduce the heat. This process typically takes around 5 minutes, but might take a little longer, so don't rush the process.
Add the garlic and fry for 30 seconds or so (be careful it doesn't burn), then turn off the heat and stir in the potatoes until coated in the butter. Add the chives, parsley, juice of half the lemon and a generous helping of salt and pepper, then toss to coat.
Taste test one, and adjust with more lemon juice and salt if needed (make sure they're well seasoned to bring out the best in the simple sauce). Serve and enjoy!
