Gin (Bombay Sapphire) & tonic.
+1 (All Gin frozen of course..)
A decent Bombay G+T, usually have to argue with bartenders to get it mixed as I like it..:
3 to 4 cubes of ice
1/3 of a lime squeezed over the ice
At least a double measure of gin (50ml) poured through the squeezed lime
Then topped up with UK schweppes (not the odd versions found in other countries)
this is also poured onto the lime that is now resting on the top of the ice.
Voila enjoy.
Yet more gin, however this would be in a classic martini:
Noilly Prat (shown the glass - small amount waved around and disposed of)
Gin - 4 oz
lemon twist
one dash Angostura bitters
Here I find Tanquery 10 to be the best readily available gin, though there are numerous specialist ones that go deliciously..
Also, some vintage Champagne..
(Personal favourite - Tarlant '98 - though it is becoming fairly meaty for a champagne now...)
