8 ounces dark brown sugar, approximately 1 cup firmly packed
1/2 cup freshly squeezed lime juice
Pinch kosher salt
Directions
Split open the vanilla pod and scrape out the pulp, and add the pod and the pulp to a small saucepan along with the brown sugar, lime juice, and salt. Whisk together and place the mixture over medium high heat and bring to a boil, stirring just until the sugar has dissolved.
Remove from the heat and allow to sit for 2 hours before using. Remove the vanilla pod.
Once cool, place the syrup in a squeeze bottle or other sealable container. Store in the refrigerator.
