Initial Christmas pud steam only 4-4.5 hours, will it be ok to store til Christmas?

[RockingMyFiftiesNot]

I posted this on the Christmas board earlier but had no responses, think perhaps better posting in food & recipes so apologies for duplication.

I've been making CP for several decades but am not expert enough to be sure about this:

I usually follow Delia's recipe, initial steaming is 8 hours. BBC GF also says 8, Nigella suggests 5.

I made my pudding yesterday, expecting to be at home most of the day. Won't bore you with why but ended up having to go out and not knowing how long I'd be, didn't want to leave the pudding steaming in case it boiled dry - thank goodness as ended up being out several hours and we had plans last night too.
Bottom line is that the pudding was steamed for 4 hours, max 4.5. I'd rather not resteam today, having fiddled with a clean, dry paper & foil topping last night.

My gut feel is that this will be ok and I'll just steam several hours on Christmas Day.
Any CP experts think that will be a problem ? Main concern is whether it will affect it's 'storability', am sure flavour will be fine if steamed for most of Christmas Day ?
Thanks

Hey! The recipe I used last year was to steam for 4 hours, then I steamed again on christmas day for another 4 hours. It fed 8 so a pretty good size. I made one for a friend and they did the same too.

It was perfect! (If I do say so myself)

Excellent, thank you. I thought it probably would be ok but thought it best to check if anyone knew why it might be an issue.

Can't beat a homemade pud!!

I think if it's not fully cooked it can be prone to going mouldy however 4 hours seems like a pretty decent amount of time. Fingers crossed!

Yes, that's the sort of thing I was worried about, but am assuming 4 hours should be ok and that the extra steaming time just enhances the flavour. It's been rewrapped in fresh dry paper so hopefully will be ok .I'll take a peak the week before and can always remake it if I have to, tho obviously would rather not!
