Muddle the Ingredients: In a cocktail shaker, add the peach slices and basil leaves. Use a muddler to gently press the ingredients together, releasing the juices and flavors. Be careful not to over-muddle the basil, as it can become bitter.

Add the Liquids: Pour in the tequila, lime juice, and agave syrup. If you like your margarita on the sweeter side, feel free to adjust the amount of agave syrup.

Shake It Up: Fill the shaker with ice cubes, cover it, and shake vigorously for about 15-20 seconds until well chilled.

Prepare the Glass: If desired, rim your glass with salt or sugar by running a lime wedge around the rim and then dipping it into your chosen coating.

Strain and Serve: Using a strainer, pour the mixture into the prepared glass filled with ice.

Garnish and Enjoy: Finish with a few fresh basil leaves and a peach slice on top for a beautiful presentation.

Sip and Relax: Take a moment to enjoy the aroma before taking your first sip!
