@Gargron i like green tea 🍵. Now i have kettle who i can decide to heat to 70/80/90°, but beforehand i used the "extra heat" from the boiling water to heat up my teapot and my tea bowl/cup, and cooling down the water on the way, pour from brewing pot into the cups/bowl and back. i also had to wait a little inbetween, but it makes the coolig shorter, and established a new routine, to avoid accidents. also an option: just mix cold water to the boiling water, fast and is close to the old routine.
