Mirabelles (also called sometimes yellow plums) are not as tart as plums can be. These small fruit goes well together with a herb like rosemary. To balance the flavors I add here vanilla, which helps to blend the flavors well without being dominating. To make it fruity I add lime juice and use again the Dr. Oetker's super gelling sugar 3:1. This sugar contains already pectin and you need on 1/3 of the fruit weight as additional sugar. The taste? I love it!
