Bring the milk with the thyme, rosemary and nutmeg just to a boil in a medium sized saucepan and set aside.
Once potatoes are cool enough to handle (but still hot), peel them and cut into manageable pieces.
Pass the potatoes through the grid of a food mill (or use a potato ricer) then into a fine mesh tamis.
Place the pan over low heat and using a wooden spatula stir the potatoes to dry them out.
Add a bit of the infused milk and fold it in.
Begin adding the butter, little by little vigorously stirring until the butter is incorporated.
Add more milk if needed. You may only need a very small amount of the milk, depending on the potatoes used, amount of butter used, and personal taste.
Keep whipping to ass the maximum air to make it fluffy.
Taste for seasoning and rectify if necessary.
That's it, that's all! Bon appétit :)
