With 3 pounds of dried plums (don't ask😁) I'm looking at plum recipes. One for prune pudding from Southern Living looks promising. It's more of a topping or fruit spread than a pudding, and I used dried plums, not dried prunes ... but close enough! Prunes are dried Italian plums ... not as juicy or round as regular plums. You see both at the grocery store. Below is the tweaked recipe.
Dried Plum Fruit Spread (or pudding if you will:)
2) Next turn on the heat, bring to a boil and simmer for 8 minutes.
3) Let cool down and transfer to a food processor or blender, add another cup of boiled hot water and pulse a few times to break the plums down, leaving some chunks. Return to the saucepan.
4) Remove 1/3 of the mixture and put it into a separate bowl to make a cornstarch slurry. This step is to avoid cornstarch lumps in the sauce.
5) To 1/3 of the plum mixture, add the juice of one lemon and stir it together. Next add 3 tablespoons of cornstarch and mix until smooth. Set aside.
6) To the main pot of plum mixture in the saucepan add 2/3 cup sugar, cinnamon, cardamom, and star anise. Stir to combine. Turn the heat back on and simmer for 5 minutes.
7) While it's simmering, pour the cornstarch slurry into the main plum mixture in the pot and continue stirring. After it thickens, remove the star anise and let the pudding/fruit spread cool.
