I mean who else can’t really always be bothered to rinse out the salsa jar and instead just tosses it away. That’s what we grew up doing. One day my father sat me down and told me not to think I wouldn’t be anything but better than him. I’m not sure how far he saw the scale above him stretch. I wonder if he dreams in feet or miles.
Grandparents knew enough to realize this surplus wouldn’t last. They scraped tinfoil and saved it for later. I do that now too, most of the time.
Works well for resting meat.
