Cranberry Sauce

Plum Sauce mixed into Quiche custard adds a savory depth that permeates every slice. The substitute should blend smoothly into the egg mixture.
Tart fruit sauce, similar sweetness
Swap 1:1 tablespoon but puree cranberry sauce smooth and temper it into 95°F cream first — whole berries sink to the bottom of the custard and leave a red ring on the crust. Cranberry's pectin thickens the filling by an extra 8%, so add 1 teaspoon more cream per tablespoon of sauce to keep the wedge tender.

Plum sauce whisked into a quiche custard at 1 tablespoon per 4 eggs gives the filling a mahogany tint and 15% more browning on the surface because its reducing sugars accelerate Maillard reactions during the 35-40 minute bake at 350°F. Blind bake the crust 12 minutes at 400°F with pie weights so the bottom does not turn soggy when the rich egg-and-cream mixture soaks in.
Temper the plum sauce into warm cream (95°F) before adding the eggs, otherwise cold sauce drops the custard below the 165°F setting threshold and extends bake time by 8-10 minutes. Unlike plum sauce on an omelet, which is applied as a surface drizzle after cooking, quiche disperses the sauce evenly through the custard so every wedge carries the flavor — an omelet treatment in quiche would sink to the bottom and leave a gummy stripe.
Pull the quiche when the center has a 2-inch jiggle; residual heat sets it golden as it cools on the rack for 20 minutes before you slice.
Don't pour cold plum sauce into the custard — temper it into warm cream at 95°F first, otherwise the filling takes 8-10 extra minutes to set and the crust turns soggy.
Avoid skipping the blind bake; the sugar in plum sauce soaks straight through raw dough and you pull a quiche with a pale, wet bottom crust that won't hold a slice.
Use more than 2 tablespoons of sauce per 9-inch quiche and the custard fails to set in the middle because the acid overwhelms the egg's coagulation at 165°F.
Don't bake past a 2-inch jiggle in the center; residual heat sets the filling and over-baking on top of the plum sauce sugars scorches the surface golden-brown to burnt.
Skip resting the quiche less than 15 minutes on a rack and the first wedge will collapse because the sauce-laced custard needs that cool-down to firm up for clean cuts.
