Step 1

If you haven't soaked dried fruit in booze ahead of time, then I would place the fruit and Frangelico in a covered bowl overnight before you start and perhaps be a bit lose with your pouring wrist when you measure out the liqueur ;)

Step 2

Beat the butter and sugar until light and fluffy then beat in the eggs.  Mix in everything apart from the flour, mixing very well. Lightly fold in the flour then scrape into a well buttered 1.4 to 1.7-litre pudding basin.

Step 3

Take a piece of baking parchment and a slightly larger piece of foil. Put a pleat about an inch deep across the middle of both then lightly grease the parchment side. Place over the pudding and secure with an elastic band or string, scrunching up the excess paper and foil around the rim of the basin.

Step 4

Lower onto the trivet inside the Instant Pot and pour boiling water to just below the level of the foil. My kettle has a capacity of 1.7-litres and I find I need most of it to come up to an inch below the rim of the pudding basin.

Step 5

Put the lid on, leave the Valve OPEN and set to Steam. As soon as you hear the steam coming out of the vent, set a timer for 15 minutes. Note that as the pot is not steaming under pressure when the vent is open, it will not start its own timer countdown.

Step 6

When the 15 minutes is up, close the Valve (use oven gloves) and set to Manual High for 45 minutes. When done, allow an NPR then retrieve the cooked pudding carefully with oven gloved hands. Remove the paper and foil and allow to cool. When cold, dry the top of the pudding off with kitchen roll then replace its covering with fresh paper and foil and leave in a cool dark place until required. This could be done a year in advance but tradition dictates at least 5 weeks before Christmas to give a full, matured flavour.

Step 7

When ready to cook, place the pudding on the trivet and pour boiling water in as before i.e. up to about one inch below the rim of your basin, setting the Instant Pot to 20 minutes on Steam (close the Valve this time). If you like your pudding extra rich and dark, you can give it 40 minutes on Steam and leave it for an hour or two on Keep Warm until you are ready for it. You can leave the pressure to release naturally and serve when you are ready on Christmas Day or if you like, do a QPR and serve right away.

Step 8

Invert onto a serving plate before portioning and serving with rum or brandy butter, custard or rum sauce mmm :D
