When the weather is cold, out comes the porridge. There’s nothing quite as warming on a chilly morning than a bowl of hot porridge. But what to do with the leftovers? In my house they go straight to the chickens but what if you could turn them into a nice hot scone for lunch? The oatmeal bannock is a Scottish creation that uses as its base some cold porridge, which really is quite unappealing – until you add some basic ingredients to it and pop it in the oven. Then it becomes a delicious scone-like cake, crisp on the outside, soft on the inside – and it tastes all the better with lashings of butter, which melt into it. And you can feel very smug for recycling leftovers. Traditionally this is cooked on a griddle but putting it into a hot oven does just as well.
