prunelle

plural prunelles

1. A kind of small and very acid French plum, especially when stoned and dried, from Prunus spinosa.

   There are oranges from Florida and Tangiers, dainty maiden blush apples from New England, figs and dates from the Levant, prunes and prunelles from Italy, candied apricots from France, and the superb English hothouse grapes, more luscious than Silenus ever crushed against his palate.
