Tracking this recipe down from my mum was like cracking the KGB, unanswered emails and phone calls that got promptly hung up. Persistence was key and ultimately she folded so I present to you my mum’s really good roast spud recipe. There’s no hot duck or goose fat to contend with instead it’s all pretty simple. Par boiling and chuffing the warm potatoes in the pot once the water is drained results in crispy crunchy exteriors and velvety interiors.
