For years I've been trying to find decent potatoes for making mash. Annie (André's mum) makes the best mash I have ever tasted and yet after years of watching her make it, I always end up with something waterier, less fluffy and less creamy somehow. Last week however, Thomas finally made something close to my beloved French mash. On investigation, it turned out he was using a type of potato I had never heard of: Wilja! It is definitely showing potential.
