How to make tiger stripes

Chill the glass for 10 minutes so the syrup clings to the sides.
Coat the glass: pour in the syrup and turn the glass so it runs around the inside.
Add ice to set the syrup on the glass.
Pour the soy milk slowly and the stripes appear. Stir before drinking.

Hot brown sugar soy

On cold days, heat soy milk to about 60–65°C (don't boil it) and stir in 15–20ml of syrup. The caramel notes come through even more when it's warm.
