Put all of the ingredients, plus a pinch of salt and pepper, into one half of a cocktail shaker, and, rather than shaking, slowly pour into the other half of the shaker, then back again. Repeat this a few times.
This will ensure that everything is well mixed. Strain into a tall glass filled with ice and garnish with a celery stick, lemon, tomatoes and olives to serve.
