Place zests, cream and milk into TM bowl and cook 8 minutes / 90 / speed 2
Allow to infuse for 10 minutes in the TM bowl before straining through a sieve into a separate container to remove solids – discard solids
Clean TM bowl and insert butterfly
Add egg yolks and sugar to TM bowl and mix 2 minutes / 37 / speed 4, scrape around bowl to collect any yolk on the sides, then continue for 3 minutes / 37/ speed 4 to make light and fluffy
Remove butterfly, add the strained liquid and blend 10 seconds / speed 4 to combine
Add the flour, vanilla, salt and cinnamon and cook 8 minutes / 80 / speed 4, then continue for a final 1 minute / 90 / speed 4
While the crèma is cooking, get your serving glasses ready, and have a tray handy to put them onto once they are filled
As soon as the crèma is cooked pour it into a jug to make it easier to dispense into your glasses, and have a flexible spatula handy to stir the mix as you pour (see next step)
Pour 150g into each glass (I use a digital scale to help me proportion evenly) and after you dispense the crèma into each glass, stir the crèma in the jug with the spatula before pouring into the next glass to keep it fluid and runny so that is pours easily and cleanly
Place small pieces of Gladwrap directly onto the surface of each crèma to prevent a skin forming
Place glasses onto a tray and allow to cool for an hour, then refrigerate for a few hours or overnight before serving
To serve, place 3 to 4 prunes on top of each crèma, pour a little of the prune syrup over the top of the prunes, then sprinkle on a few maple roasted pecans if using
If you wish you can serve extra prunes in a small bowl on the table for guests to help themselves to if they want more (like me!)
