Rhubarb Cream

Ingredients

Directions

Prepare the rhubarb

  1. Place the rhubarb in a saucepan and add enough water to cover it.

  2. Stew until it becomes a pulp.

Set the cream

  1. Dissolve the gelatine in a small amount of hot water, then add it to the rhubarb pulp.

  2. Stir in the sugar and add the lemon rind or juice.

  3. Rinse a mold with cold water, pour in the rhubarb mixture, and let it firm up.

Serve

  1. Turn out the rhubarb cream onto a glass dish and serve with boiled custard around it.

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. Rhubarb + lemontop 7% of all pairs

    Shared aroma: acetic acid (sour, vinegar).

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

    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

Rhubarb
Provides the tart flavor and, once stewed, the pulp that forms the body of the cream.
Gelatine
Sets the pulp so it holds its shape when turned out of the mold.
Sugar
Sweetens the tart rhubarb and balances its acidity.

The step that matters

Dissolving the gelatine. Gelatine must be fully dissolved in hot water before it is added to the pulp; undissolved granules leave specks and weak patches, and it sets properly only when evenly distributed.

Swap the rhubarb

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

  1. Cinnamonfits better
  2. Gingerfits better
  3. Marjoramfits better
  4. Rhubarbthe original

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