Peach Surprise

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the custard

  1. Scald the milk in a double boiler.

  2. Stir in the cornstarch mixed with a little cold milk.

  3. Remove from heat and stir in the butter, egg yolks, and sugar until creamy.

Assemble and bake

  1. Drain the juice from the peaches and place the peaches in a baking dish.

  2. Cover the peaches with the milk mixture and bake in a 400°F (200°C) oven for 10 minutes.

  3. Remove from the oven and spread the stiffly beaten egg whites sweetened with powdered sugar on top.

  4. Return to the oven to brown.

  5. Serve with the sweetened peach juice.

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

What each ingredient does

Milk
Forms the liquid base of the custard that is poured over the peaches.
Cornstarch
Thickens the milk as it heats, giving the custard body.
Egg yolks
Thicken and enrich the custard, adding richness and a creamy texture.
Butter
Adds fat for richness and a smoother mouthfeel in the custard.
Sugar
Sweetens the custard.
Peaches
Provide the fruit base and the juice served alongside the dessert.

The step that matters

Stir in the cornstarch mixed with a little cold milk. Cornstarch mixed with cold liquid first disperses evenly, so it does not clump when added to hot milk. It thickens only when the mixture is heated, so the custard needs to be kept hot enough for the starch to swell.

Swap the peach

How well each one fits the dish's main ingredients (milk, butter, egg, sugar):

  1. Vanillafits better
  2. Figfits about as well
  3. Coconutfits about as well
  4. Peachthe original

Fit is the average pairing score against milk, butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
