Rhubarb jam in a tefal jam maker

Ok so doing a batch now, have done the extraction but my book lists another 40 mins on top for cooking time. This seems slightly ott plus it doesn't say add in the paddle which I have done.

Any urgent help available 

Probably too late to offer advice, but you've lost nothing by keeping it and seeing how it turns out - you can always bin it anyway at that point, all you've got to do is wash the jars again?

I've spent this afternoon doing rhubarb / date / raisin chutney that looks decidedly liquid, rhubarb muffins, and a rhubarb 'hot cake' (it's gone cold now) which is basically a flat pie with rhubarb and sugar between two layers of pastry. 

And I still have a lot left .... 

oh no! You have just reminded me to check my rhubarb! (it is tucked away in a corner) 

Hmm - interesting 4ft high plant with flowers ....   

and I like rhubarb jam too
