In making a Margarita (straight-up), what is the first ingredient added to the shaker?

In a Margarita, the correct first ingredient to add to the shaker is lime juice. This is because lime juice is a crucial component that balances the flavors of the drink; it provides the necessary acidity and brightness that complements the other ingredients.

When making a Margarita, the sequence of adding ingredients can impact the overall mixing process. Starting with lime juice allows for a better emulsification with the spirits and mixers that follow. This order ensures that the ingredients blend well and that the lime juice’s fresh flavor permeates the drink effectively.

Lime juice is often highlighted for its importance, as a fresh squeeze of lime can elevate the taste of the Margarita significantly, making it a refreshing choice, especially when served straight up. It's common practice in cocktail making to add more delicate ingredients, like fresh juices, early in the mixing process to allow them to meld seamlessly with the stronger flavors of alcohol.
