Step 1

Prepare black sugar simple syrup: 1:1 ratio of black sugar slab to water. You can usually find black sugar at Asian grocery markets, but a good replacement is dark brown sugar.

Step 2

Prepare boba pearls and thickened black sugar syrup: Make a second 1 cup batch of thicker black sugar simple syrup starting with a 1:1 ratio of black sugar to water and reduce till a thick syrup. This takes around 5-7 min of boiling the mixture on medium heat after the sugar has dissolved. Make sure to constantly stir to avoid burning. Set aside to cool. Prepare 1.5 cups of boba pearls per package directions. After placing the boba pearls in cold water, add the boba directly to 1 cup of the cooled black sugar simple syrup mixture and mix to combine. Set aside for later. You can often find premade boba at Asian grocery stores. If you cannot source boba pearls, just make the reduced black sugar simple syrup.

Step 3

Prepare a Collins glass with 2 tbsp of the syrup-soaked boba pearls. Tilt the glass horizontally and rotate 360 degrees to fully coat the inside of the glass with the black sugar syrup.

Step 4

Add Mr Black, Suntory Whisky Toki, whole milk, and vanilla extract into a shaker.

Step 5

Fill shaker with ice and shake vigorously for 15 seconds.

Step 6

Strain the shaker into the prepared Collins glass and serve with a boba straw.
