  • Only buy what you need

    By writing a shopping list you tend to stick to the food you need rather than be tempted by what you don't! This is a simple way of avoiding buying food that wasn't planned and then end up going in the bin.

  • Know your dates

    Remember that an 'Expire date' is the last day a product is safe to consume. whereas the 'Best before date' is an indicator for the quality of your food. It tells you that after this date the food is no longer in perfect shape, it might have lost freshness, taste or aroma. But that doesn't necessarily mean the food is no longer safe to eat.

  • The Power Of The Senses

    Use your senses before throwing out a product that has passed 'best before date'. Often by looking, smelling and tasting food, your can get a sense of whether it really needs to head to the bin.

  • Order your fridge

    Simply by placing food that is soon to expire at the front of your fridge, you are more likely to use it up before it gets forgotten about and goes bad.

  • Save your yellow cheese block

    Did you know, if you find a little mould on your yellow cheese you can cut it away and enjoy the rest? Just cut off at least 2.5cm around and below the mouldspot and ensure the knife does not touch the mould part, as it could then contaminate other parts of the cheese.
