For the asparagus martini, wash the asparagus and cut it into coarse pieces. It is not necessary to peel it, as we only want to extract the flavor. Now fill the asparagus with the other ingredients into a small iSi Whip bottle and close it with the Rapid Infusion attachment and the small strainer. Then fill in a CO2 capsule and let it infuse for 20 minutes. If you don't have an iSi Whip bottle handy, you can simply let the mix infuse overnight in a sealed jar in the refrigerator. This requires more planning but tastes just as good as the faster iSi Rapid Infusion version.To serve, first let the gas escape from the iSi Whip bottle before unscrewing it. Now strain the asparagus martini into a mixing glass with ice cubes and a piece of lemon peel. Stir the martini until cold and then strain the drink into a chilled glass. As a garnish, serve a thin strip of asparagus, which you simply cut from the asparagus with a peeler. Cheers and here's to life!
