Peaches Raspberry Ice

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the base

  1. Peel and slice the peaches.

  2. In a saucepan, combine peaches, raspberries, sugar, and water.

  3. Bring to a boil, then simmer for 10 minutes.

  4. Remove from heat and stir in lemon juice.

Freeze

  1. Cool the mixture, then strain it into a shallow dish.

  2. Freeze until firm, stirring every 30 minutes to break up ice crystals.

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.

    Shared aroma: trans-2-nonenal (cardboard, fatty).

  2. Peach + sugartop 17% of all pairs

    Shared aroma: beta-damascenone (apple, rose).

    Shared aroma: 2-nonenal (fatty, green).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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

Peaches
Provide the main fruit flavor and natural sweetness, and body as they cook down.
Raspberries
Add tart, bright fruit flavor and color to the mixture.
Sugar
Sweetens the ice and lowers the freezing point, keeping it softer when frozen.
Lemon juice
Adds acidity that brightens the fruit flavor and balances the sweetness.

The step that matters

Freeze until firm, stirring every 30 minutes. Stirring breaks up ice crystals as they form. Without it, the ice sets hard and coarse with a grainy texture instead of a smooth, fine-grained one.

Swap the lemon

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

  1. Vanillafits better
  2. Apricotfits better
  3. Pearfits better
  4. Lemonthe original

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