Raspberry Water Ice

Ingredients

Directions

Prepare the juice

  1. Press out the juice from fresh raspberries.

  2. In a saucepan, combine 1 pound of raspberries, 2 tablespoons of sugar, and 2 tablespoons of water, and stir until it boils.

  3. Rub the mixture through a sieve to obtain the juice.

Make the ice

  1. In a bowl, mix the raspberry juice with 2 teaspoons of lemon juice and ½ pound of sugar boiled with ¼ cup of water until syrupy.

  2. Put the mixture in a freezing pot and freeze in the usual way.

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: alpha-pinene (pine, turpentine).

    Shared aroma: 2,3-butanedione (butter, sweet).

Lemon and sugar 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

Raspberries
Provide the flavour and the juice that forms the body of the ice.
Sugar
Sweetens the ice and lowers its freezing point so it stays soft rather than rock-hard.
Lemon juice
Adds acidity that brightens the raspberry flavour.

The step that matters

Dissolving the sugar syrup fully before mixing. Sugar dissolved in water lowers the freezing point and controls ice crystal size. If the syrup is undercooked or not fully combined with the juice, the ice can freeze hard and grainy.

Swap the raspberry

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

  1. Orangefits better
  2. Limefits better
  3. Vanillafits better
  4. Raspberrythe original

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