Scientists designed color-changing carbon dot biosensors that can detect spoiled meat in sealed packages in real-time, just in case you don't trust the sniff-test.

That date means nothing. It's a best by date, not an expiration date. It's just the last date you can get a refund if it goes bad.

But I've had a gallon of milk last a whole month after the best by date.

Yeah, the date on the package means even less if you freeze it. Frozen meat is good for years.

(Freeze your ground beef, freeze your bread. Throwing away food is expensive!)

Yes, and freeze sauces, soups, and stews in ice cube trays and then into freezer bags for easy portioning later. This was life changing advice for me.

This is why I can! I don't have enough freezer space!

I live in an apartment with a very small fridge that has a tiny freezer inside it. I got a small chest freezer that I use for storage. I only use the one in my fridge for freezing stuff, then it moves to the chest freezer.

Do you do meal planning and if so do your plans include your frozen stuff?

When I have energy I sometimes make ravioli or lasagna and freeze it! But it requires energy and freezer space.

We use these for soup:

Pricey for glorified ice cube trays, but really convinent to have the soup portioned to size.
