How to Make It
Pack the peach wedges into a 1-quart glass jar. In a small skillet, toast the coriander seeds over moderately high
heat, tossing, until fragrant, 2 minutes. Let cool, then crush the seeds.
In a medium saucepan, bring the vinegar, water and molasses just to a boil. Stir in the garlic, ginger, salt, orange zest, piment d’Espelette and crushed coriander seeds. Pour the brine over the peaches and let cool completely. Cover and refrigerate for at least 4 days before serving.
