How to Make Green Tea Shots?

It is easy to make green tea shots. However, its preparation differs from other teas because it does not require boiling water to produce. The boiling water has a negative effect on its making as it turns the taste of green tea leaves bitter. Hot or simmering water at a temperature of 150 to 180℉ is enough. Green tea also has a steeping time of only 20 to 30 seconds, beyond which its taste becomes unpalatably sharp. Therefore, only hot water is needed to make it, and additives like sugar, cream, etc., remain unnecessary. A little bit of lemon juice can sometimes be added to some varieties for taste modification. The various green teas have different infusion times and temperatures, so each variety should be prepared accordingly. Again, the packet should be referred to for the instruction details.
