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.

  1. Strawberry + rhubarbtop 5% of all pairs

    Cooked together193 recipes

    Shared aroma: methyl cinnamate (strawberry).

  2. Rhubarb + lemontop 7% of all pairs

    Shared aroma: acetic acid (sour, vinegar).

  3. Strawberry + lemontop 15% of all pairs

    Shared aroma: 3-hexenal (apple, fruity).

  4. Sugar + lemontop 18% of all pairs

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

  5. Rhubarb + sugartop 18% of all pairs
    Smell alikemoderate
    Cooked together1,852 recipes

    Shared aroma: 1-penten-3-one (fish, pungent).

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

Strawberry rhubarb
Provides the main flavor and tartness, and breaks down into a pulp when cooked.
Sugar
Adds sweetness, balances the tartness, and keeps the frozen texture smoother.
Lemon juice
Adds acidity that brightens the flavor and sharpens the fruit taste.

The step that matters

Cook the rhubarb until very soft. Rhubarb must break down completely so the mixture strains smooth. Under-cooked rhubarb keeps stringy fibers and leaves a gritty, uneven texture in the frozen ice.

Swap the lemon

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

  1. Vanillafits better
  2. Blueberryfits better
  3. Figfits better
  4. Lemonthe original

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