Oh right, thanks! I had to laugh as by the cooker I had a relatively large empty bottle waiting!! Wishful thinking there!
So I should probably strain just at the stage where, if I run a knife through the liquid it leaves a space where I can see the pan - if that makes sense? I did do it piping hot, but of course it took so long that it was cold by the time I'd finished!
Can I still use it with those teeny tiny bits of seed in it?
