Rim the Glass: Start by running a lime wedge around the rim of your glass to moisten it. Dip the rim into a plate of coarse salt and set the glass aside.

Prepare the Jalapeno: Place the jalapeno slices into your cocktail shaker. If you prefer a milder drink, remove the seeds before adding.

Muddle: Use a muddler to crush the jalapeno slices gently. This will help release their spicy and flavorful oils.

Add Ingredients: Fill the shaker halfway with ice. Pour in the tequila, fresh lime juice, Cointreau (or Triple Sec), and simple syrup.

Shake: Secure the lid on the shaker and give it a good shake for about 15-20 seconds. This will ensure all the flavors mix well and the drink gets chilled.

Strain and Serve: Strain the mixture into your prepared glass filled with fresh ice.

Garnish: Decorate your cocktail with a lime wheel and some extra jalapeno slices.

Enjoy: Sip on your spicy creation and relish the layers of flavors!
