Limmer's Gin Punch (English)

This is a version of the drink for which Limmer’s Hotel in London was most famed: a Captain Gronow recalled it in his 1860s memoirs as one of the top, if filthy and seedy, sporting hangouts of 1814, thanks in part to its ‘famous gin-punch’. A bartender named John Collins worked there later in the 19th century, and was famous enough to inspire a limerick, so many believe he created the Collins, which is similar to gin punch, although the drink is not named in the rhyme which goes as follows: 

My name is John Collins,
head waiter at Limmer’s,
Corner of Conduit Street,
Hanover Square,
My chief occupation is filling
brimmers
For all the young gentlemen
frequenters there.

2 shots Bombay London dry gin
¾ shot lemon juice, freshly squeezed
¾ shot Monin Pure Cane sugar syrup (65°brix, 2:1 sugar/water)
2 shots mineral water, chilled 
1 dash Angostura aromatic bitters

All all ingredients into a punch bowl.  

Fill with ice and garnish with citrus slices.
