There is a variety of recipes for the whole family to enjoy, quick suppers to rustle up after work, and impressive dishes for when you entertain. Some are tried and tested favourites with a new twist, others use a selection of new ingredients or flavour combinations. Mary knows the details in a recipe that make all the difference. Discover them in Mary Berry Cooks the Perfect.
