Invented in the 1980s in New York, not France. It's French because it uses Chambord, which is super French. It tastes like a smooth raspberry, pineapple tart, but with Vodka! and that's why we like it.
50ml Vodka (Nice Vodka)
35ml Pineapple Juice (Again, the nicer the better)
Pour everything into a cocktail shaker and fill it with ice. Shake it! Chambord suggest with the 'vigour of a Tambourine' but like a polaroid picture is fine.
Fine strain into a martini glass.
Your French Martini should have a nice foam on the top and taste a little creamy.
