There was a British type of Gauloises, but I gave up when King size went to 50p a packet of 20. Cigaloos or some name like that.
The tea pot is only rinsed out, the brown coating helps make a good pot, but any item used where milk is added, needs cleaning, so if drinking without milk, yes just rinse the cup, but if adding milk, then needs a problem clean, I am told milk stops the goodness of the tea, so should never be drunk with milk, sugar is OK but not milk.
As soon as milk is added, then not proper tea, so question as to milk or tea bag first is pointless, as should not have any milk to start with. With other infusions I would never dream of adding milk, as to mixtures, like Earl Grey, is it really a tea, or is it just an infusion?
