A quick tip to help keep your kitchen / fridge/ pantry more organized is to keep everything in the same place all the time.
IE: eggs go in the same spot; milk has its spot, bread etc... They all have there “homes” in the fridge, freeze, pantry etc.
This way when you go to write out your shopping list, if you look in the milk spot and you are out of milk you will know that you are really out of milk! Not have to search the fridge to see if it’s in another spot!
