Did you also know, that if you can get your eggs from a farm if they are NOT washed, they will keep weeks longer? Most small farmers know not to wash the protective coating off their eggs, but I’ve seen some people selling free range eggs that are washed before they are readied for sale.
I had heard that.
We keep our fridge COLD. We turn it down until the milk freezes then bump it up until the milk stops freezing. It ends up being about 34F.
Milk, eggs, and leftovers keep FOREVER in our fridge.
I remember when I was a teen, they had a picture of a thermometer on the side of the milk carton with the shelf life in the fridge listed for every degree F from 33 to 40.
I can’t find anything like that now, but IIRC, it seemed like it doubled the shelf life for every degree F you lowered the temperature.
