Christmas pudding in instant pot-please help!

[tillytubby]

I've just bought an instant pot and decided to cook the Christmas pudding in it.
I've followed my usual Delia recipe which is a big 1.75ltr
The only recipe I could see online with similar weight (everynookandcranny) said to steam it for 15 mins then pressure cook for 45mins. But it didn't look cooked!
So I gave it another 45mins.
Is that enough?
How can I tell it's cooked?!

We cooked our Christmas pud in instant pot too (though it was actually DH who made them).

We used veg suet so it took longer about 2 hours i think, and they had gone all dark inside and looked like proper Christmas puds. Plus they get steamed again on Christmas Day.

I would love to know this OP, can you let me know timings when you find out? Fingers crossed it is cooked. Would a clean skewer work?

Can you over cook a Xmas pud? I guess in an instant pot, it's possible. But traditionally, you can steam for hours and hours. So I think, if in doubt, put it back in would be my motto.
