Making the Simple Syrup

• 1). Mix 2 cups water and 2 cups sugar in a saucepan over high heat.
  
  
• 2). Bring the mixture to a boil.
  
  
• 3). Reduce the heat to a simmer and stir until the sugar is completely dissolved and the mixture is clear.
  
  
• 4). Pour the mixture into a lidded container (such as a jar) and refrigerate. It will keep for about two weeks.
  
  

Mixing the Margarita

• 1). Fill a cocktail shaker with ice.
  
  
• 2). Cut a small slice from the half lime and set it aside. Take the larger part and squeeze as much of the juice as you can into the cocktail shaker.
  
  
• 3). Add a teaspoon of the chilled simple syrup to the shaker.
  
  
• 4). Add 1 1/2 ounce of silver tequila and 1 ounce of Cointreau, triple sec, or other orange-based liqueur.
  
  
• 5). Shake until cold (usually 15 seconds is enough).
  
  

Preparing the Glass

• 1). Take the small slice of lime you set aside earlier and make a small cut from the edge to the center. The slice should fit on the edge of the glass so the center of the lime is at the glass's rim.
  
  
• 2). Rub the lime around the rim of the glass, squeezing slightly. The whole rim of the glass should be lightly covered in lime juice.
  
  
• 3). Sprinkle salt onto a plate. Roll the glass in the salt, shaking away any excess. The rim of the glass should end up lightly coated with salt.
  
  
• 4). Pour the margarita into the glass and enjoy!
