For those looking to customize The Baby Assassin, consider adjusting the proportions of its ingredients to tweak the flavor intensity or alcohol content. For a slightly sweeter taste, you might increase the amount of Sambuca. To lower the alcohol content, you could substitute one of the liqueurs with a non-alcoholic syrup of a similar flavor or simply decrease the quantities of each alcoholic ingredient and substitute the volume with a mix, such as a citrus soda, for a lighter version.
