In a flat container/plate, mix some salt and lime zest. Rub a lime along the edges of a double rocks glass and rim the edges with the salt lime zest mixture. Keep aside.

To a mixing glass, add the avocado, jalapeno, mint and lime juice; muddle well till the avocado is completely mashed.

Then add the tequila, Grand Marnier, salt and sugar syrup. Fill the mixing glass with icecubes and shake till well-chilled.

Add more ice cubes to the serving glass and strain into it.

Garnish with lime, jalapeno slice and fresh mint leaves.
