Do exactly what you're doing (which is exactly what I do), right up until the simmer bit.
Now, when you've got your rice to a rolling boil, let it carry on boiling hard for FIVE (count 'em, 5) minutes, with the lid on. After 5, kill the heat (if you're on electric, shame on you, and move it to another element), KEEP THE LID ON, and leave it to stand for another 10 mins.
Then all it should need is a quick whip through with a fork, and you're sorted.
Tilda is teh bestest, but it should be possible to get halfway decent rice out of the others...
That sounds like good advice
will try this next time, but I guess you've also noticed the difference between Tilda and other rices by what you said?
