The Daiquiri is a classic cocktail made with three simple ingredients: LIME, RUM, and sugar. The LIME is a citrus fruit that is widely used in cooking and cocktails, and it is the main ingredient in the Daiquiri. RUM is an alcoholic beverage made from sugarcane byproducts, and it is the second ingredient in the Daiquiri. Finally, sugar is added to balance out the tartness of the LIME and the strength of the RUM. All three ingredients are essential for making a classic Daiquiri.
