Tapwater here is unboilable owing to the calcium. I filtered my water for 20 years using Brita, but now have a Franke system inline. No scum on my tea.
Sainsbury extra strength.
In a pot it is 4 bags plus one bag of Chai. Boiling filtered water from the Franke. Onto the hob at mark 3. After a minute squeeze the bags individually and bin.
Pour. Add lacto-free semi skimmed.
Drink.
You get 3 cups from my pot. Drink within ten mins.
For a one...
