Make a list of what’s next to use!
I keep a list taped on the inside of a cupboard door, with everything that will likely go over soon listed. (To be honest, some things on my list are past their “best before,” like the tea, but it can still be used!)
At the bottom of the list I have a space where I keep track of how many days it’s been since I’ve had to throw out food.
This way, I am regularly reminded of what I’m trying to use up next, and motivated to use it because I don’t want to break a waste-free streak!
