When I drink black tea it's with milk, using freshly boiled water (allow bubbling to stop) in a preheated cup. Milk gets added after steeping so as not to scald. For the love of all that's holy, don't microwave the water. Use a kettle or a pot.
Green and most herbal tea gets neither milk nor sugar, but sometimes honey. Add a little cold water to the herbs first, so you don't extract bitter compounds: using near 100C water is why so many people think they dislike green and herbal tea. (Ginger, hemp, chamomile and hibiscus are the main exceptions to this rule - they need boiling water for the floral flavours.)
I love coffee, but I have enough herbal tea to open an apothecary. Just be careful that you're not getting teabags with plastic in them! Pukka are consistently great, as are Suki.
Favourite fancy biscuits are from the Island Bakery [0] in Scotland. Their Lemon Melts and their Chocolate Gingers are just about perfect. I know you can find their shortbread in the US, but not sure about other varieties. The biscuits come in a little cardboard boat and it's adorable.
What's your favorite biscuit. Asking as a yank who likes tea and biscuits.
