Overnight oats

SIR – I eat porridge every day at home (Letters, September 6).

When away I substitute overnight oats. These are oats soaked in milk or water and eaten cold: no cooking involved, and still delicious. Susan Whitehead

SIR – It is not only hotel chefs who struggle with this simple dish. I have just seen frozen porridge on sale in my local supermarket. Marie-louise Neill
