Ceasar's Imperial Cocktail

This is the first of the recipes that we tried from the cookbook Cooking With Asterix, my beautiful Thai Bride thought it looked tasty. To make a nice presentation, dip the rim of glasses in the juice of half a lemon, then in sugar and allow to dry, and decorate with a slice of orange. We found this to taste mostly of grapefruit juice, next time we'll likely half the amount, or omit it altogether. Grenadine syrup is flavoured pomegranate syrup, used mostly in cocktail drinks. I imagine that you can double or triple this recipe, as is, it makes four large glasses worth.
