Peel potatoes, cut into 1 cm slices.

Put butter and buttermilk in a bowl large enough to accommodate potatoes. Microwave to melt butter. Don't worry when buttermilk looks curdled.
Using a potato ricer, rice potatoes into hot buttermilk/butter.
Fold liquid into riced potato until just mixed, do not overwork. If too dry, add a little more buttermilk and butter.
