Curds and whey in milk

[rosiemuggins]

For nearly 60 years I have enjoyed a mug of cocoa before going to bed. I make the drink with boiled milk. For decades I had no problem but during this past year the milk (semi-skimmed) often turns into curds and whey and I have to throw it away. This now occurs about once a week.
I no longer buy large bottles of milk and this happens days before the "use by " date.
Is anybody else experiencing the same problem?
Any ideas?
Many thanks.

check the temp of your fridge, in warm weather the milk can turn before its date if not kept cool enough.

It seems to me that you are overboiling your Milk which has a higher boiling point than water. Over boiling will cause curdling and if I was you I would bring your Milk gently to the boil in your Saucepan or mix Cold Milk and Cocoa in your Mug and heat up in Microwave, stirring occasionally.

Thanks for your replies but they do not solve the problem. I have been making my cocoa in exactly the same way for over 50 years but it is only in the past year that the milk has curdled in such a revolting way.

tut tut tut redman41, never put milk in the microwave!!
well thats what i heard years ago, will have to check why though,
personally i prefer soya milk with my cocoa, out of curiosity, whats your fave cocoa, i used to like ovaltine, now i use a 100% cocoa powder from a health food shop

I like a cup of cocoa too last thing, avoid all this milk business by buying cadbury's hot chocolate sachets, Tip one in a cup fill with boiling WATER and enjoy.
As a tip add half a teaspoonful of instant coffee in stir well, & you've got a hot cup of Mocca. (V/tasty)

In reply to Piggynose, my favourite flavour is Rowntree's cocoa.

Following on from Piggynose's remark, I understand that liquids can superheat in a microwave without actually boiling and then they rapidly start to boil and explode when being removed from the microwave oven.
Lots of people have been badly scalded by the above.
