Apple Float

Ingredients

Directions

Cook the apples

  1. Place the apples in a pot and cover with water. Stew until they are soft.

  2. Remove the apples and add sugar to the same water. Bring to a boil.

  3. Return the apples to the pot and stew until they are clear and tender.

Make the syrup and set it

  1. In a separate bowl, dissolve gelatin in cold water. Squeeze in the juice of the lemon.

  2. Mix the gelatin and lemon juice into the syrup and bring to a boil.

  3. Pour the syrup over the apples and let it cool until it congeals.

Add the custard and meringue

  1. For a custard, whisk together egg yolks, powdered sugar, and milk. Spread over the apples when cold.

  2. Whip the egg whites, flavor with lemon, and place on top of the custard. Brown in the oven.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Apples
Cook until tender, then hold their shape and provide the fruit base of the dessert.
Gelatin
Sets the cooled syrup so it congeals into a firm, sliceable layer.
Egg yolks
Thicken the milk mixture into a custard that sets when cooled.
Egg whites
Whipped into a light foam that forms the top layer and browns in the oven.
Sugar
Sweetens the syrup and helps form its body as it reduces.

The step that matters

Letting the syrup cool until it congeals. Gelatin only sets once it cools below its setting point, so the syrup must be fully cooled and firm before the custard is spread on, or the layers will mix.

Swap the apple

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

  1. Vanillafits better
  2. Orangefits better
  3. Figfits better
  4. Applethe original

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