Pie Plant Custard Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the egg yolks, butter, stewed pie plant, sugar, and flour until well combined.

  3. Pour the mixture into a prepared pie crust and bake until set.

Make the meringue and finish

  1. In another bowl, beat the egg whites until soft peaks form, then gradually add 3 tablespoons of sugar and continue beating until stiff peaks form.

  2. Spread the meringue over the baked pie and return to the oven to brown the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the filling as they set, giving the custard its rich body.
Egg whites
Whipped into a foam, they form the meringue topping that stays light and airy.
Stewed pie plant
Supplies moisture and tart flavour that balances the sweetness of the custard.
Sugar
Sweetens the filling and, in the meringue, helps the whites hold stiff peaks.
Flour
Helps stabilise the custard filling so it sets smoothly rather than weeping.

The step that matters

Beating the egg whites to stiff peaks. Under-beaten whites collapse and weep under the topping, while over-beaten whites turn dry and grainy. Sugar added gradually dissolves and stabilises the foam, so the meringue holds its shape and browns evenly.
