Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

What each ingredient does

Prunes
Provide the main fruit body, sweetness and a soft, jammy filling once mashed.
Sugar
Adds sweetness and helps soften the fruit into a smooth, spreadable filling.
Lemon
Juice adds acidity that brightens the sweet prunes, and the rind adds fragrant aroma.
Pie crusts
Enclose the filling on both sides, giving structure and holding the juicy mixture while it bakes.

The step that matters

Ensure the mixture is juicy. The prunes must release enough liquid to keep the filling moist as it bakes. If it is too dry, the filling can turn stiff and pasty, and if it is too runny, it can soak the crusts and make them soggy.
