Monroe says that by doing this, it’s “revolutionised” the way she cooks and shops and has also reduced a lot of anxiety around food, impulse purchasing and food waste while also keeping the food bill low.

“It also helps me plan balanced meals, and sparks off all kinds of avenues of creativity,” she adds.

In the thread, Monroe acknowledges that this method is “useless” for those who have nothing in the cupboard but hopes it is of use to someone – particularly those who want to save a bit of money on their food shop.

“It’s quite laborious the first time you do it, but as someone who has lived in food poverty, I find it quite powerfully reassuring to have a physical list of all of the food I have.”

Many shared their thoughts on the thread, along with their own methods of organising their food shopping in order to reduce costs.

“I do exactly this and run a spreadsheet for the fridge, freezer, larder,” wrote one. “My columns are protein, ready meals, home frozen vegetables, commercial vegetables, sweets, date frozen and date use by.”
