fresh cherries for muddling and garnish
Instructions
In a drink shaker add tequila lime juice, water, cherry syrup and shake with ice to get the drink ICY cold.
If you cherries are really ripe the syrup will be flavorful and sweet, if they aren't super flavorful muddle 6 cherries in the drink shake and strain as you pour the drink into the glasses. (alternatively you can muddle 10 or so cherries per drink and you will want to adjust the sweetness with simple syrup then)
Pour over a rimmed glass with lime and salt and half full of ice.
Garnish with a cherry.
Notes
alternative: You can muddle fresh cherries and add additional sweetener if you don't want to make the cherry syrup. But trust me, once you make the syrup you fill find lots of things to enjoy it on.
