Spiced Shiso Syrup
Add sugar and water into a small saucepan over medium heat until sugar dissolves.
Add the spices into a small pan over low heat and toast until spices become fragrant. Be careful to not burn.
Add toasted spices into the simple syrup, remove from heat and let come to room temperature. Once the syrup has cooled, remove cinnammon and star anise.
Meanwhile blanch the shiso leaves in a pot of boiling water for 15 seconds, then remove and immediately place into a bowl of ice water. Pat dry and set aside.
Add the simple syrup and shiso leaves into a blender and blend well for about 1 minute. Strain any bits out with a fine mesh strainer or cheese cloth. Store the refrigerator.
