How to Make It
In a medium saucepan, combine the plums with 1/2 cup of water and bring to a boil. Simmer over moderate heat, stirring often, until the plums are falling apart, about 20 minutes. Add the sugar and garlic and cook, stirring, until the sugar is dissolved, about 2 minutes. Remove the relish from the heat and let cool.
Meanwhile, in a small skillet, combine the savory, coriander, Aleppo pepper, fenugreek and cinnamon. Toast the spices over moderate heat, shaking the pan, until fragrant, about 1 minute.
Stir the spices into the compote and season with salt and pepper. Scrape the compote into a bowl, cover with plastic and refrigerate until well chilled, about 2 hours. Fold in the cilantro, scallions, parsley and tarragon before serving.
