Pruneaux à l’Aigre-Doux (Sweet-and-Sour Prunes)

For Pâté de Campagne

In place of the expected cornichons, pruneaux à l’aigre-doux go with pâté de campagne, particularly this pâté de campagne from southwest France, which is also the home of the especially good pruneaux d’Agen.

250 gr (½ lb) of pitted prunes, preferably pruneaux d’Agen

150 ml (⅔ cup) red wine

100 gr (½ cup) sugar

70 ml (⅓ cup) red-wine vinegar

Combine the prune…
