El Presidente is a simple and fun variation of the Daiquiri. In this recipe, the Daiquiri's simple syrup is replaced with pineapple juice and grenadine. The result is a semi-sweet tropical cocktail.
If you like, skip the cocktail glass and serve it tall and on the rocks. You may also want to save the grenadine for a drizzle after straining. This would transform the drink into something similar to a Tequila Sunrise. This is a fun combination to play with, so do it!
