I used to love tea with one sugar but since being diagnosed diabetic type 2 have had to stop having sugar in my cuppa tea.
Don’t miss chocolate and white bread that much, but the sugar in my tea, yep I sure do miss that!
Oh, to answer your question, not a big fan of earl grey tbh, Rooibos is quite nice but I tend to go for the standard tea bags, whichever is on offer at shops but I find I like green tea with a drop of lemon.
But since moving to hard water area that the hard water definitely affects the tea flavour.
Soft water is much better for flavoursome tea imho.
Ooh, hang on, I have a RO system now……can I use RO pure water for making tea with I wonder?
