My dad makes the best margaritas! He just made these for my birthday and they were such a treat to have. My dad takes his time in both making these and consuming them and sees them as a special treat. If you want to impress your friends or family at a party or for a Mexican themed dinner try this recipe!


3 oz tequila

2 oz Triple Sec or Cointreau

1 slice of lime placed in each glass

Half of a lime squeezed (so juice from half a lime)

1 and 1/4 cup Costco Kirkland Non Alcoholic Margarita mix

1 splash of Grand Marnier on top of each drink (optional, Ron wants you know this creates the “Cadillac” part)


  1. In a cocktail shaker with a bit of ice combine 3 oz tequila, 2 oz Triple Sec or Cointreau, juice of half a lime and 1 1/4 cup Costco Kirkland non alcoholic margarita mix.
  2. Put a lime and ice in each glass.
  3. Shake and serve over lime and ice. Put a tiny splash of Grand Marnier on the top of each drink.
