Ok, have been on a mission since yesterday to get this out of my cupboard! Mission now accomplished. Discovered yesterday that if you make a single cup with 2 teaspoons of tea instead of just one and steep it for 5 minutes, it has flavour! So I finished off the last two teaspoons of tea this morning. Milk, touch of maltiness, nice.
Not going to bother purchasing any more English Breakfast of any kind for a long time I think.
