Recalling what you need without a grocery list can be challenging. However, simply taking photos of your fridge and pantry before you go grocery shopping can prove helpful.

This is an easy way to ensure you buy exactly what you need for upcoming meals and you’ll be able to avoid the unwanted frustration of forgetting essential items as well.

This hack is particularly useful in preventing waste when purchasing pricey perishables like fresh salmon. Keeping these reference photos also helps cut down on aimless browsing.

Additionally, knowing exactly what’s in your pantry (and how much space you have) makes it easy to take advantage of major discounts on shelf-stable goods when bought in bulk.
