Remembering both vermouth and gin are flavoured with similar botanicals, they obviously have an affinity for each other. This drink may be simple but made...
This was my father's favourite cocktail, a taste acquired by him in the 1920s-30s. I used to mix it for him under his instructions and tried it myself only a few years ago, but now my favourite too. Different gins and vermouths can make a huge difference to taste, but never bad, just different. He also taught me vermouth is pronounced to rhyme with 'Portsmouth', never 'Vamoof'!!
