Fill the Glass with Ice: Start by filling a highball glass with ice cubes. This will chill the drink and help create the layered effect.
Add the Tequila: Measure 2 ounces of tequila using a jigger and pour it over the ice in the glass.
Add the Orange Juice: Measure 4 ounces of orange juice and pour it into the glass over the tequila. If using fresh oranges, squeeze them using a citrus juicer for the best flavor.
Add the Grenadine: Slowly pour 1/2 ounce of grenadine into the glass. To achieve the sunrise effect, pour the grenadine slowly over the back of a bar spoon. It will sink and then slowly rise through the orange juice, creating a gradient effect.
Garnish and Serve: Garnish the drink with an orange slice and a maraschino cherry. Serve immediately and enjoy your refreshing Tequila Sunrise!
