Something to warm you up

It's bloomin horrible weather so here's a reminder of something warm and sugary to cheer you up.

Blackberries covered in sugar...

 brought to the boil...

and roll-boiled...

 but not boiled over until it cools and...

gets made into one of the most beautiful milkshakes ever! It's like a scene from outer space.
Enjoy the sight without the calories  = )
