The cost of the weekly food shop is so much higher than it used to be, with prices of lots of items unrecognisable from just a year or two ago. It means making every pound spent on grocery shopping go further and reducing waste have never been more important, especially when you consider the climate crisis too.

With this in mind, supermarket giant Tesco has offered some valuable advice that could help your wallet as well as cut down on waste.

In an effort to prevent us from prematurely throwing away kitchen essentials, the supermarket titan has shared some useful tips on its website, including on bananas: freeze them to enjoy at a later date.

"Using your freezer for just ice cubes and a packet of frozen peas? Wondering whether you can freeze milk?" Tesco asks on its website, adding: "Freezers are the most efficient when they are full, so make the most of the space to prevent food waste and have ingredients ready to go. From milk and cheese to veg and rice, your freezer can do it all!"

When it comes to ripe bananas, Tesco suggests peeling them before freezing them either whole or sliced up. When you're ready to use them, they can be taken straight from the freezer and are perfect for adding to smoothies or providing the base to a homemade ice cream.

Milk

Pop it in the freezer and you’ll never need a last-minute dash to the supermarket again. If full or unopened, pour a little bit out of the container before freezing so that it has room to expand as it freezes, or tip into an airtight container. Defrost overnight in the fridge and shake well before using to mix the milk and fat back together, then use as normal.

Cheese

Hard cheeses like Cheddar, Red Leicester or Comté all freeze well if you are clearing out the fridge.

Eggs

You can freeze eggs. Crack into a small bowl and whisk together, then freeze in a freezer bag or individual ice cube trays – defrost for omelettes and baking whenever you need. You can also freeze just the whites ready for meringues.

Potatoes

If you’ve got too many to use before they start to sprout, peel, roughly chop and blanch until just cooked, then spread out on a tray so they’re not touching. Freeze until solid, then tip into a freezer bag – roasties ready to go!

Yoghurt

You can easily freeze your spare yoghurt at home. If you’ve got kids, pop a lolly stick in mini yogurts ready for summer snacks at a later date.

Wine

If you don't finish a bottle of wine, pour the remainder into ice cube trays (or a freezer bag if you have a larger amount), then add as cubes to recipes as needed.

Herbs

Roughly chop soft herbs, place in ice cube trays and top up with water, then simply defrost when ready to use, or drop whole into pasta and curries.
