A neat/poncy
trick to make your latte look a bit different
Firstly, you froth the milk like mad - needs to be as stiff as you can get it. Then pour it into a glass (this is important, as your drinking vessel must be transparent for this to be effective).
Whilst your frothed milk cools, it should begin to visibly separate into unfrothed milk (bottom), and frothed milk (top).
Make a shot of espresso & slowly pour the piping hot coffee into the cooled milk. If you're careful, the coffee will sit between the two milk layers. Et voila - one layered latte.
Principles behind it are elementary physics, (hot fluids less dense than cool ones) - but it looks pretty cool until you stir the sugar in!
