Instructions

Rinse a 15 cm (6 inch) square container with water. Whisk the agar into 500 ml cold water in a saucepan until no lumps remain.
Bring to a gentle boil over medium heat, then boil for 2 minutes, stirring constantly, to dissolve the agar completely.
Pour into the container, pop surface bubbles, and cool at room temperature for 1 hour.
Cover and refrigerate for at least 3 hours until firm.
Syrup: simmer the brown sugar and 100 ml water for 5 minutes until slightly thickened. Cool and chill.
Turn out the jelly and cut into long strands about 3 mm thick with a sharp knife, or press through a noodle press.
Divide the noodles among chilled bowls, spoon the syrup over and dust with kinako.

Tips

Boil the agar for the full 2 minutes or the jelly will be soft and cloudy.
Cut the noodles into long square strands for the classic look.
Use cold bowls to keep it refreshing.
Good with cold barley tea.
