Why frozen raspberries are good for you

There's nothing like raspberries to brighten up a cold, dark January day. Of course, the fresh sort will be jet-lagged, scarily expensive and disappointingly flavour-free. But at this time of year frozen, preferably British, raspberries really come into their own.
The freezing process accentuates their sharp, fresh flavour, and they retain their seductive perfume, providing a refreshing contrast to stick-to-the-ribs winter food. They're perfect after Christmas when you can't work up any enthusiasm for autumn's apples and pears, and clementines and satsumas are turning dry and fibrous.
