Why it works: Rhubarb and vanilla match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 276 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Rhubarb Jelly Cups
Ingredients
Directions
Make the rhubarb jelly
Cook rhubarb until soft, then press through a sieve to measure 1 quart.
While hot, add enough sugar to sweeten to your taste.
Soak 2 tablespoons of gelatin in 2 tablespoons of cold water.
Stir the gelatin mixture into the rhubarb until dissolved.
Pour the mixture into small cups.
Let the cups set until firm.
Serve
Unmold the jelly.
Scoop out wells in the center.
Fill the wells with vanilla ice cream.
Arrange the jelly remnants around the base.

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):
- Cinnamonfits about as well
- Rhubarbthe original
- Nutmegfits less well
- 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.
