Step 1: Prepare the glasses
Run a lime wedge around the rim of each glass, then dip into coarse salt or sugar depending on your preference. Set the glasses aside to let the rim set.

Step 2: Make the peach purée
Blend fresh or canned peaches until smooth. If the purée is too thick, add a splash of water or lime juice to thin it slightly. Strain for a smoother texture if preferred.

Step 3: Add everything to a shaker
Fill a cocktail shaker with ice. Add the tequila, peach schnapps, peach purée, lime juice, triple sec, and simple syrup (if using). Shake vigorously for 15–20 seconds until chilled and well combined.

Step 4: Taste and adjust
Taste the mixture before pouring. If you prefer it sweeter, add a little more simple syrup. For extra tartness, add a splash more lime juice.

Step 5: Serve over ice
Fill the prepared glasses with fresh ice, then strain the margarita mixture evenly into both glasses.

Step 6: Garnish and enjoy
Garnish with a peach slice, lime wedge, or even a sprig of mint. Serve immediately while cold and fresh.
