Warabi mochi is a unique dessert made up of jelly-like chunks coated in nutty roasted soybean powder and drizzled with rich black sugar syrup. It's served cold and is one of my favourite Japanese sweets!
Line a container with plastic wrap and a light sprinkling of water. Transfer the warabi mochi to the container and leave to cool. Once cool, chill in the fridge for 1 hour.
On a medium heat, bring to a boil. Once boiling, reduce heat and simmer for 2-3 minutes until thickened. Remove any foam that forms around the edges and remove from the stove.
