Mustard Mash

This is a regular side order at the Sugar Club and is unbelievably popular – we’ve probably served three potato paddocks’ worth since we opened! Simple mash is a wonderfully comforting food and adding flavours to it – whether as pesto, olive paste, roast puréed field mushrooms or carrot purée – only increases its appeal. Sue Fletcher at Hodder & Stoughton promised they would publish the Cookbook so long as this recipe was included, so here it is.
