Sorry typing error, next door key, of course it should be Maris Piper but neither I nor anybody else noticed the typing error. Well done to you:thumbsup:
Mrs BG uses Naris Piper potatoes as an essential, par boils them and fluffs them up in a colander or the saucepan and lets them get cold. Sets the oven at 220 and puts cold oil over them then place in the oven. End result lovely crisp roasties to die for.
