Holiday Bavarian Pie

Bavarian cream is the chilled, lighter-than-air French dessert that sits halfway between mousse and panna cotta, and this holiday pie version sets it into a baked shell with a generous splash of rum. Make it the day before, top with whipped cream right before serving, and you have a centerpiece dessert that takes nothing off your hands during the actual meal.

The technique is part custard, part mousse. Egg yolks are tempered into a milk-and-gelatin custard over a double boiler, the rum stirs in off the heat, and the whole thing chills until it mounds from a spoon. Beaten egg whites and softly whipped cream get folded in one at a time to lighten the custard into a pillowy filling.

Do not skip the chilling-to-mound stage. Folding the whites and cream into a still-loose custard breaks them down into a thin liquid that will not set tall in the shell. You want it just thick enough to hold a soft peak when you drop a spoonful back into the bowl.

Pro Tips

• Cook the custard over hot but not boiling water. Direct boil heat scrambles the yolks instantly. The custard is done the moment it coats the back of a spoon.
• Bloom the gelatin in cold milk for five minutes before adding to the eggs. Dry gelatin clumps if dropped straight into hot custard and you get rubbery threads in the slice.
• Beat the egg whites to firm-but-glossy peaks, never bone dry. Dry whites break apart when you fold and ruin the silky texture.
• Top with the second half cup of whipped cream just before serving. Whipped cream weeps if it sits on a chilled pie for hours.

Variations

• Swap rum for bourbon or amaretto for a different boozy backbone matched to your holiday cocktails.
• Drizzle with grenadine in a spiderweb pattern instead of shaved chocolate for a striking red-and-white finish.
• Use a chocolate cookie crust in place of plain pastry for a black-and-white Bavarian pie.
