Boil potato quarters until tender (but not mushy). When cool enough to handle, peel skin (discard) and set aside.

Place Margaret Holmes Diced Rutabagas in a large glass bowl and scatter butter cubes. Microwave for 2 minutes (stirring once half way through).

Add parsley and the white rose potatoes to the warmed rutabagas, and smash with a potato masher until mixed (small chunks should remain). Season with salt & pepper.
