Bubble and squeak - How to not waste food

How to not waste food – Food wastage is when food that could be eaten by us has been left to go off or is discarded. Certain measures can help reduce this waste. These include doing a food audit, reducing portion sizes, freezing extras, and using leftovers in other recipes.

Before shopping for food check what you already have including items in your fridge, and freezer. Be aware of food approaching their use by and best before dates, try using these and perishable foods first. The difference between “use by” and “best before” date is: Use by date – this is about the date up to which the food is safe to eat; best before date means the food may not be of best quality after this date.

Top tips on reducing food wastage

When shopping include fresh foods that keep longest, and those with a longer shelf life. Being organised in the kitchen will help you keep track of foods that are ready to eat. Cooked food that is not eaten is also a waste, reducing portion sizes can be useful. Begin with a smaller portion, people can always have second helpings. If there are left overs use them with other recipes. Also plan ahead of the quantity you need to cook. Freezing extras can help preserve food for longer. These measures should help reduce food wastage.
