Roly-poly Pudding

Ingredients

Directions

Make the dough

  1. Make a rich pudding paste with flour and butter, mixing in enough water to form a smooth dough.

  2. Roll out the dough thinly to a width of 8 to 10 inches.

Fill and roll

  1. Spread a thick layer of jam on the dough, leaving an inch around the edges bare.

  2. Roll the dough around the jam tightly and twist the ends to seal it.

Boil and serve

  1. Wrap the roll in a floured cloth and boil for 2 to 8 hours, depending on size.

  2. Serve hot, cutting it crosswise.

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: isobutyraldehyde (malty, green).

  2. Butter + raspberrytop 16% of all pairs

    Shared aroma: delta-decalactone (sweet, creamy).

    Shared aroma: isobutyraldehyde (malty, green).

Flour and butter barely smell alike, yet cooks put them together in 124,287 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

Flour
Forms the dough's structure, giving the paste body to hold the jam while it boils.
Butter
Adds fat that makes the paste rich and tender rather than tough.
Raspberry jam or currant jam
Provides sweetness and fruity flavour, and moisture that soaks into the surrounding dough.

The step that matters

Rolling and sealing the roll. If the dough is rolled unevenly or the ends are not sealed well, jam can leak into the cloth during the long boil. Thin, even dough also cooks through more consistently.

Swap the raspberry

How well each one fits the dish's main ingredients (flour, butter):

  1. Raisinfits better
  2. Vanillafits better
  3. Coconutfits better
  4. Raspberrythe original

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