Most people don’t know the use of the plastic grass that comes with sushi take-out. It’s actually a divider to preserve the flavors of the sushi and keep them fresh as possible.
So Eat Happy Sushi pushed this “freshness” aspect to another level by replacing the plastic material to litmus paper – which can indicate how fresh the sushi is. The color of the paper grass will change gradually depending on the freshness of the sushi, leaving no leftover sushi behind.
