Leftovers are awesome. Casseroles, pasta sauces, roasts, chocolate mud cake – they always taste better the day after. Of course, some things aren't so good – wilted lettuce soggy with yesterday's dressing comes to mind. Leftovers also need to be stored correctly. Cooled uncovered on the bench, wrapped, and promptly tucked away in the fridge. And they should be consumed within a few days. If something's been in your fridge for more than a week, or you can't remember when you cooked it, it needs to be chucked!
