I think I have decided I like Tanqueray better than Bombay Sapphire, but alas it is so long since I have had any of the yellow label export-only Gordons that I cannot say whether I would like that better still, and of course the stone-bottled Bols yonge genever is great too.

I have decided I prefer a slice of lime to lemon, and the tonic just has to be Schweppes.

I keep the gin in the freezer and the tonic on the fridge (on the verge of freezing, it's a cold fridge) and two ice cubes cold enough to stick to the fingers...

In a tumbler, half gin, half tonic.

What do others do?
