You could save up to £900 according to this Orpington mum, who gained a mega following on Instagram with her money saving freezer tips.

Kate Hall, a mum from Orpington, has created a name for herself online by sharing money saving food hacks and goes by the name The Full Freezer on Instagram with over 70,000 followers.

According to AO.com, Brits were found to be binning a whopping £450 of food every year, with 10 percent of every adult's weekly shop binned, leading to huge amounts of food waste a year.

However, Kate has shared some of her top money saving tips that could save Brits up to 900 a year on food waste.

Here are her top tips:

Fruit and Veg

The Instagrammer, who shared her food saving tips with over 78,000 followers on the app, said that one of the biggest culprits of food waste was fruit and veg.

According to the mum of two, Brits could save themselves up to £272.48 a year, or £5.24 a week, if they simply froze their fruit and veg to reduce waste.

According to AO.com, fruit and veg are thrown out 53 times a year, which could be avoided through this simple but effective hack.

Kate explained: “Most people don’t realise that you can freeze fruit and veg at home. Whilst they won’t defrost well, frozen fruits can be blitzed in smoothies or used in baking, and veg can be used in cooked dishes.

“For fruit, simply wash, dry, and chop up as appropriate and freeze it on a lined tray before moving to a freezer bag. This way it won’t freeze in a solid clump.

“The same technique can be used for veg, although some vegetables such as broccoli and cauliflower are best ‘blanched’ before freezing.

“Once you’ve blanched your veg, open-freeze it just as described for fruit, and always cook it straight from frozen for the best quality.”

Bread

Another big contender for food waste was found to be bread, racking up to £72.80 worth of waste a year, with this staple food item found to be thrown out 51 times a year.

Whilst bread should not be put in the fridge to avoid it going stale quicker, Kate explained that bread could be frozen in freezer bags with people able to take out slices as needed.

Kate said: “These slices can be toasted straight from frozen, or defrosted at room temperature. Just be sure to keep the bread wrapped whilst it thaws so it doesn’t dry out.”

Milk

Now it’s no surprise that many of us have probably had leftover milk that’s gone off.

But these little dregs of milk rack up to £33.90 per year, with milk found to be thrown out 47 times a year.

However, according to Kate, milk could be salvaged from spoiling by decanting in into a bottle and storing it in the freezer for smaller and usable portions.

The milk can then be defrosted and used in things like porridge or tea.

Kate added: “Milk can sometimes look yellow when frozen and may split when it defrosts, don’t be put off by this, it’s just the fats separating from the water. Give it a good shake and it'll come back together.”

Meat and fish

Another huge culprit for food waste in our fridges was revealed to be meat and fish, with a massive £249.60 worth of waste a year, with unused meat and fish thrown out 43 times a year.

Kate suggested that people should consider how to use it and store it into smaller portions in cases like minced meat, fish and sausages to avoid excess waste.

Kate said: “A simple hack is to freeze the raw leftovers spread out in the original packaging, just be sure to enclose this in a freezer bag, and freeze away from ready-to-eat foods to avoid any cross-contamination.

“Once the meat or fish are frozen solid you can remove the packaging, squeeze the air out of the bag and seal.”

Yoghurt

On average Brits were found to throw out yoghurt 41 times a year, amounting to £43.16 of this dairy produce wasted every year.

Although yoghurt isn’t one that defrosts well, Kate suggested to freeze yoghurt in smaller cubes to be used in things such as smoothies or lollies, or plain yoghurt frozen in freezer bags to be used in cooking.

Potatoes

Brits were found to throw out potatoes 38 times a year, racking up to £46.28 worth of food waste.

Most people wouldn’t think spuds could be frozen, but according to Kate you can freeze your unused potatoes, although unlike other vegetables they can’t be frozen raw.

Kate advised to freeze potatoes by making them into a mash and adding them to flat freezer bags to be used as ready-made mash.

However, if mash isn’t your thing, potatoes can also be frozen as baked jacket potatoes, by baking them and allowing them to cool before freezing them.

A final suggestion was to roast your potatoes before freezing them, to have ready-to-go homemade roast potatoes the next time you fancy a roast dinner.

Stock

Although stock isn’t a huge contender for food waste, Brits were found to throw out stock 37 times a year, amounting to £13 worth of waste every year.

Stock leftovers can be frozen by boiling stock down until you’re left with a quarter of the original amount, before freezing them in an ice cube tray to have smaller portions to use when cooking.

Kate said: “If you usually end up with more stock than you need, freeze any leftovers. To save on space, it’s worth boiling your stock down until you’ve got around a quarter of the original amount, then once it’s cooled, pour it into an ice cube tray. When it’s frozen, you can transfer the cubes to a freezer bag or sealable container to store and use them straight from frozen in your cooking.”

Cheese

It’s no mystery that many of us Brits love cheese, with this item being a staple in our food shops.

But Brits were found to waste £108.42 worth of cheese every year, with it being thrown out 36 times a year.

But cheese can be frozen to use in cooking, and hard and semi-hard cheeses can be grated before freezing to use at a later date.

For semi-soft cheeses like mozzarella, Kate recommended cutting them into bitesize pieces to be used on pizzas and pasta before cooking.

Soft cheeses can also be frozen into smaller portions to be wrapped up, before freezing them to use at a later date.

Kate explained: “Softer cheeses should be portioned into usable quantities and tightly wrapped before freezing to ensure they are well protected from the cold air.

“When you want to eat them, thaw them slowly in the fridge before moving to room temperature to serve.”

Eggs

You might not be able to put all your eggs in one basket, but you can put them all in one freezer.

On average Brits were found to waste £64.48 worth of eggs every year, with them being thrown out 36 times a year.

But eggs can in fact be frozen by adding some salt or sugar to the yolk to prevent it from turning gloopy.

Eggs can also be frozen whole by breaking them out of the shell and whisking them before freezing, and storing them in a muffin or ice cube tray.

Herbs

Finally on this list, we’ve all had a time where we’ve had herbs that have gone bad, but herbs that were wasted were found to cost Brits £65 a year in food waste.

Once frozen, herbs can’t be used as a garnish, but herbs can be frozen for use in cooked dishes by storing them in a freezer bag, or with water or oil in ice cube trays.
