Funny!
I don’t shake it - but I have noticed that over the last 20 years, milk stays good a lot longer in the fridge than it used to do.
When I was a kid, 1950’s-60’s, we got our milk from a little local dairy that delivered it to us every day - there was a little silver ‘milk box’ outside our front door for the delivery man to leave the milk and other dairy in.
Once in a while, the milk would taste very onion-y or garlick-y; my grandmother would say that the cows had gotten into the grass...
Sealtest delivered our milk, buttermilk, cream, and butter. They provided the galvanized steel box for their deliveries to the back porch.
Recall those odd grey boards glued to the insides? Cement asbestos board insulation.
Cows brouse on grass and will eat yard onions and wild garlic, both will flavor their milk. It can be quite strong.
I have 7 crockpots of varying sizes. I too like to cook breakfast and load something in the pot for supper at the same time. Almost any low temp oven recipe can be adapted - just reduce the liquids a bit to modify.
I have even cooked beans in my 2 qt. size. I use several crocks to make stuff and keep it warm when we would have lots of people for holidays.
I miss those days of milk delivery. They stopped here in the late 60s. I really liked the non-homogenized milk with the cream on top.
I would skim off that cream and use some to make butter. A fast dessert/treat was to open a can of home canned blackberries (canned in sugar syrup) and put a couple of spoonfuls of cream on top, stir and eat.
