I've made these a few times and substituted the Rose syrup with Lanique (a Sweet roes liqueur).Also I generally prefer Don Julio over Patron so used the blanco and triple sec. With these changes this is an excellent drink. Today I received the bottle of Diffords saline solution I ordered and tried adding two drops.. wow. I have just finished reading David Arnold's "Liquid Intelegence" and whilst I have many times read of Simons passion for adding a drop or two until to day I hadn't realised. Wow
