Directions

Make the rhubarb jelly

  1. Cook rhubarb until soft, then press through a sieve to measure 1 quart.

  2. While hot, add enough sugar to sweeten to your taste.

  4. Stir the gelatin mixture into the rhubarb until dissolved.

  5. Pour the mixture into small cups.

  6. Let the cups set until firm.

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: methyl cinnamate (strawberry).

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

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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

Rhubarb
Provides the main flavor and body of the jelly once cooked and sieved.
Gelatin
Sets the rhubarb purée into a firm jelly that holds its shape when unmolded.
Sugar
Sweetens the tart rhubarb to the cook's taste.
Vanilla ice cream
Adds cold, creamy contrast to the warm-fruit flavor of the jelly.

The step that matters

Stirring the gelatin into the rhubarb. Gelatin must be fully dissolved before the mixture cools, or it will set unevenly and leave grainy or rubbery pockets in the jelly.

Swap the rhubarb

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

  1. Cinnamonfits about as well
  2. Rhubarbthe original
  3. Nutmegfits less well
  4. Peppermintfits less well

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