P.S. In the old days when the housewives cleaned the steps with “donkey stone” they used sour milk to wipe over afterwards and it is reported to “dry like ivory”.

If you need to use the milk for cooking put some cream into the milk and that will make it edible (or drinkable).

Use when making scones - very traditional

Make it into yoghurt!

Boil it (to get rid of all germs), let it cool to just warm, add some plain yoghurt and let it sit in a semi-warm place for a day or so.

Milk just beginning to sour is the perfect kind to make butter. Just whip it well past the peek stage. It’ll start to separate. What you have is the old style or “european” butter. This won’t work with 2% or skim milk.

Add it to the dough for pancakes dough or fried pastries.
