Make the Strawberry Honey Syrup
Combine 1 cup of hulled and sliced strawberries with ½ cup of honey, and ¾ cup water in a small saucepan over medium heat.
Bring the mixture to a bubble, reduce the heat to low, and allow the mixture to cook until the berries are soft.
Remove from heat.
Using a potato masher, crush the berries in the pot.
Allow mixture to sit and cool for 5-10 minutes.
Pour berry mixture through a fine mesh sieve placed over a bowl.
Discard the berry remnants in the strainer.
Cool the syrup completely before using in your cocktail.
