Start by rolling and juicing your oranges, then strain them to remove all the pulp so your drink is smooth and delicious.
Load up a highball glass with ice.
Pour in your tequila of choice and orange juice.
Gently pour your grenadine over a spoon to allow the liquids of different densities to slowly mix and create the iconic sunrise colours in the glass.
Garnish with a slice of your orange and enjoy.
