About the only things that get binned from the freezer are the things that are visibly freezer burned or things that I’ve had so long that I recognize I’m probably not going to use them and I’m tired of moving them around. Some meat (especially BS breasts, which I consider a staple) some veg (particularly Costco frozen stir fry mix… also a staple), and bits I save for stock. (The offspring no longer recoils from bags of wing tips, back, and feet, even if he thinks it looks like Sweeney Todd lol)
Fresh meat I’ve gotten pretty good at gauging what we’ll go through in a week. I have a real butcher shop here where I can buy just enough for two of us, so that’s good.
I struggle with fresh things. I buy the lovely things (from local/family sources when I can), but time and energy leave them untouched and I end up pitching them. I’m getting better, but I have a ways to go.
No dairy at my house, but I use the dates as a gauge of how scrupulously I need to sniff it before I use it. Sauces and dressings with a long-passed expiration get tossed simply because if we haven’t used it since then, we ain’t gonna.
