A stylish birthday celebration in central London starts at dusk with an Amaretto sour. 

For this exquisite cocktail you will need:

Ice a plenty

4 fresh lemons

Homemade sugar syrup

2 shots Amaretto

Orange peel

Shake everything except the ice in a kilner jar for ease (particularly useful when you’re in Trafalgar Square)  Taste with your thumb over a straw  and add more lemon, Amaretto or syrup depending on your mood.

Serve over serious amounts of ice and admire the view of the giant purple cockerel.
