Purple Plum Chiffon Pie

Fresh purple plums simmered and pureed into a vibrant base, then folded with whipped egg whites and cream into a billowy chiffon filling that sets in a baked pie shell. This is a no-bake filling that’s all about the fruit, lightness, and texture.

The plum puree carries the entire flavor profile. Simmering 1¼ pounds of halved plums until tender concentrates their tart, slightly floral sweetness. Sugar and lemon juice balance the puree before the gelatin goes in, so taste it at that stage and adjust.

Getting the gelatin timing right is the make-or-break moment. Dissolve it over hot water, then chill until it’s slightly thickened but not set. Too liquid and it won’t hold the whipped whites and cream. Too firm and you get lumps of gelatin in an otherwise silky filling. It should be the consistency of raw egg whites when you fold everything together.

Pro Tips

• Use ripe, dark purple plums for the deepest color and sweetest flavor. Underripe plums are too tart and pale even with added sugar.
• Beat egg whites to stiff but not dry peaks. Over-beaten whites break apart when folded and leave grainy streaks in the chiffon.
• Fold gently in three additions. Stir a quarter of the whites in first to lighten the base, then fold the rest in two batches to preserve the volume.
• Chill at least 4 hours before slicing. The gelatin needs time to set fully or the filling will ooze when cut.

Variations

• Spiced plum chiffon: Add ¼ teaspoon each of cinnamon and cardamom to the plum puree for a warming, autumn-spiced version.
• Graham cracker crust: Swap the pastry shell for a graham cracker crust for a crunchier, sweeter base that pairs well with the tart plum.
