Lemon, Lime and Bitters is a mixed drink made with
lemonade, lime cordial, and Angostura bitters. The lemonade is sometimes
substituted with soda water or lemon squash, which is more akin to what
is called "lemonade" in North America.
The exact origin of Lemon, Lime and Bitters is unknown, however it is
claimed to have been invented and popularized within Australia sometime
around 1880. Consequently, LLB is commonly consumed in Australia and New
Zealand where it became customary for golf players to have a drink of
LLB after a match of golf.
My favourite brand is Bundaberg. Bundaberg Lemon, Lime and Bitters is
craft brewed over 7 days using real lemons and limes that are infused
with aromatic herbs and spices.
