Depends how I feel at the time of making but it always has to be Yorkshire Tea! At work we buy in bulk a big bag of PG Tips and just eww! They don't taste nice so I buy my own box of Yorkshire Tea for work. At home I also make sure we always buy Yorkshire Tea.
At work when I'm rushed, I have to squeeze the teabag. This is not my preferred method though, because I find that it just doesn't really get strong. At home and if I get the chance at work, I will leave the teabag to soak for a couple of minutes, add some milk (not too much! not a fan of milky tea!) and definitely NO sugar!
