Now, pour the 2 oz of tequila and 4 oz of orange juice into the highball glass and give it a very slight stir.
Gradually pour the 1/2 oz of grenadine around the inside edge of your highball glass and let it sink and slowly rise to mix with the other ingredients of the drink naturally. The mixture of the ingredients in a unique way will gives a great colourful sunrise effect in the glass.
Your Tequila Sunrise Cocktail is ready to serve, garnish it with an orange slice and a maraschino cherry and present.
