Today I wanted to go with something pretty and I'm a sucker for layered drinks.
Fill a glass with crushed ice
Pour 2 oz. amaretto over the ice
Slowly add 3 oz. orange juice (if you pour too quickly, it'll mix and you'll lose your layers)
Slowly add 3 oz. club soda (see above note)
Add a dash of grenadine
Garnish with an orange slice and/or a cherry
