Make the strawberry puree. Add 4 cups of strawberries, ¼ cup of sugar, and one tablespoon of lemon or lime juice to a food processor or blender. Blend until smooth. Store leftover puree in a mason jar for up to 4 days in the refrigerator.
Make the simple syrup. Add equal parts sugar and water to a saucepan. Bring the sugar mixture to a boil, reduce heat, and simmer until the sugar has completely dissolved. It should take about 5 - 7 minutes.
Prepare the margarita glasses. Using a lime, wet the rim of the glass. Immediately after wetting the rim, gently place it onto the plate with salt. Tilt and rotate the glass, pressing the rim into the salt to allow it to adhere. Ensure that the salt covers the rim thoroughly and evenly.
To a cocktail shaker, add strawberry puree, tequila, orange liqueur, jalapeno rounds, and simple syrup. Shake or stir until well combined.
1/4 cup Strawberry Puree, 4-5 Jalapeno Rounds, 2 oz Tequila, 1 oz Cointreau, 1 oz Simple Syrup, 1 oz Lime Juice
Pour margarita into the prepared salt rimmed glasses. Garnish with strawberries and extra jalapenos. Enjoy!
