So I know it may sound a bit weird, but I like milky tea with some lemon juice added. I pop a teabag into the mug, fill it about 2/3 with boiling water, let seep a bit, remove teabag, add some freshly-squeezed lemon, then slowly add cold fat-free milk (and add stevia for sweetness). How can I make myself a cuppa without the milk curdling? 
I use lemon zest in my tea while its steeping, then I strain it through a fine strainer. Gives you all the benefits and no curdling.
