Brew lightly. I was served this in the Betty’s of Harrogate flagship store tearoom and they scalded the tea so it went bitter, which is a shame, because it tastes so lovely and delicate when brewed correctly. I pour a little cold water on the tea shortly before pouring on the nearly-boiling water.
It’s also fun to brew this in a glass teapot, because the little coils unwind one by one. :>
