Meet the woman who reckons she saves more than £1,000 a year - by freezing ingredients individually. Kate Hall, 37, says realising you could freeze ingredients on their own was a "lightbulb moment". She has previously been freezing entire meals which, when reheated, could only be used once. But Kate, from Orpington, Kent, now has a constant "stash" of ingredients in her freezer - meaning she can always use the right amount and reduce waste.
