Final answer:
In a house margarita, blanc or silver tequila is typically used for its ability to blend with lime and orange liqueur. The specific brand chosen can be based on the establishment's preferences or inventory.
Step-by-step explanation:
When preparing a house margarita, the type of tequila used can vary depending on the restaurant's recipe or the individual's preference. Generally, a blanco or silver tequila is chosen for its clean, crisp flavors that blend well with the tartness of lime juice and the sweetness of orange liqueur. For instance, common brands used could include Jose Cuervo Especial, Sauza Silver, or Patron Silver. It's important to select a tequila that complements the balance of flavors in the cocktail while adhering to the cost requirements of the establishment.
Keep in mind, the specific brand or type of tequila used in your house margarita may be dictated by the establishment's standards or the inventory available. If this is a question from a workplace, referring to your employer's recipes or bartender's guide is recommended to ensure consistent quality and taste for customers.
