Melt a whole stick or 1/2 cup butter into a pan and saute 3 to 4 chopped shallots until they almost start turning golden. In the meantime, boil fingerling potatoes, drain and with the back of a heavy serving spoon, give a smash or a pop. Sounds crazy, but that what I do, only being careful to just smash the top not the whole potato. Put potatoes into the butter and shallots and give a good stir with plenty of salt and pepper. Season with Herbs de Provence.
