Step 1

Combine the strawberries, lemon juice, and simple syrup. Allow berries to release juice by sitting in the liquid at least 30 minutes.

Step 2

Add the strawberry mixture to the blender and run it on low (I used the sauce feature on my Blendtec). You can really blend it as much/little as you like, but I found this mode made it perfectly pulpy with a bit of foam. Add whiskey and swirl to combine.

Step 3

Pour over ice and serve.
