Years ago, I discovered that when I write a list, the contents are ingrained in my memory and I don't need the physical list anymore. It has worked with shopping lists and recipes as well as unrelated things to be remembered.
Particularly useful when giving hour long lectures. Worked better than some of the lectures I suffered through as an undergraduate where some dozy professor read out the same lecture he'd been reading out every year for the last 40. One rather famous prof managed to fall asleep in the middle of his own lecture.
Now I just struggle to remember where I put my jar of black garlic or whatever.
