Looking at previous blog entries, I can't believe I haven't mentioned this one before - perhaps because it is such a timeless classic, I just presume everyone knows it. But if you don't, do make yourself one, it is such a perfect, delicious drink. We use 2 parts of Gordon's Gin to 1 part each of Cointreau and freshly-squeezed lemon juice and gomme/sugar syrup to taste - we use around half a part syrup, but start with less and taste until you get the level of acidity you can bear. Shake on ice, and serve in a martini glass with a lemon twist. Perfect accompaniment to smoked salmon blinis.
