A shopper who believes she saves more than £1,000 a year on food says freezing ingredients individually is the secret to reducing waste.<br /><br />Kate Hall, 37, from Kent, says she used to freeze entire meals which, when reheated, could only be used once, but had a “lightbulb moment” after realising freezing ingredients individually allowed her to always use the right amount.<br /><br />She says this limits her trips to the supermarket and saves money as her frozen produce could be used time and time again.
