A sweet-tart plum sauce that is fluid enough to use as a topping and yet still thick enough to add a spectacular red swirl as a mix-in for ice creams and gelatos. Use fruit on the verge late summer over-ripeness – it’s worth waiting for those fragrant plum bursting with juice!
1 1/2 lbs plums*
Pitt and roughly cut the plums into chunks (for very ripe fruit just tear it apart with your hands) Heat the plum chunks (including skin) in a heavy saucepan over medium heat. If the fruit is very firm, break it up with a spoon periodically as it cooks. Keep on a low simmer (turning down the heat if necessary) for 8-10 minutes until the fruit has released its juices and looks mushy.
Using an immersion blender (or standard blender*) to puree the fruit thoroughly. Push the mixture through a fine-mesh strainer, pressing down on the solids and cool.
Combine all the plum swirl ingredients into a small saucepan and bring to a simmer over medium heat. Cook for 10-12 minutes, stirring occasionally until the mixture thickens.
