After placing the passion tea bag in this jug, pour it into a cup of boiling water.

Let the mixture stand and allow the tea to steep for 10 minutes. Let the mixture cool at room temperature.

In the meantime, remove the teabag from the jug and dispose of it off.

In the very next step, pour the blueberry juice into your water mixture.

Also, mix soy sauce and vanilla extract in the jug.

Mix well to combine your Starbucks-style blue drink.

Fill a glass with ice cubes and serve your blue drink cold.
