Can't help with the nuts aspects (don't eat nuts of any sort; loathe and detest them !) but as regards the pork I do not think that cooking separately will work -- the flavours need to infuse into the pork, which they can't do if it is seared and cooked separately. What is your reason for not wanting to cook the pork in the korma sauce ? You could always par-cook it (with spices, of course) separately in advance if you are concerned that it may not cook sufficiently in the sauce.

My fears are that cooking the pork in the sauce will either make it tough or not cook all the way through. I've never timed the korma recipe but it's really quick, on high heat and has cold stuff added to it frequently until the end of the recipe.
I don't want to simmer it too long after everything has been added because I just do not know what it will do to the taste and texture. There's fresh fruit puree in there as well.
There's only one point in the recipe where you leave the sauce to simmer for a while but it's 3 minutes tops.
It could work if the cubes of pork were about 1 by 1 cm, but I think that's too small.
I could take your par-cook idea, but cooking it with spices will mess with the end flavour of the sauce which I've put so much time into getting right.
But I'm no expert so maybe you know a solution?
I can post the recipe if you'd like.
Thanks for lending your ear.
