Ok ok, I gave this another shot and it turns out I was doing it completely wrong the first time. The first few times, I had it with just sugar and it as giving me a bitter taste.
I gave a few tea bags t my friend who said she looooved it with milk and sugar. SO. I gave it another shot, this time with milk and sugar. Game changer. Now it tastes much creamier and sweeter. I just needed the milk to cancel out the bitterness I was tasting. I only wonder why I didn’t think of that myself.
