I, staff Haruna, joined a spice seminar organized by a big spice company in Tokyo.
The theme was – “Add Spices to Your Drink”.
2 tbsp sugar
1/2 tsp cinnamon (powdered)
1/4 tsp cardamom (powdered)
1/4 tsp nutmeg (powdered)
This spice sugar can be added to any drink, coffee, black teas…but I am not sure about Sencha though!
