So, work are sending me to London for three days every week for the next six months, and there's a studio flat they're putting me up in. If I buy a pint of milk every week it goes off, cos I only use it for a cup of tea in the morning and maybe a bowl of cereal one day every two weeks. So can I pour milk into those ice cube bags, and then just tear off a cube or two for a cuppa? How long would the milk last?
