Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Bind the batter and add structure as they set during cooking.
Butter
Adds fat for a rich flavor and a tender crumb.
Flour
Provides the starch and gluten network that gives the pudding its body.
Baking soda
Reacts to release gas that lifts the batter as it cooks.
Sugar
Adds sweetness and helps keep the crumb soft.
Raspberry jam
Adds fruit sweetness, acidity, and moisture to the batter.

The step that matters

Add the baking soda last and mix well. Baking soda must be evenly distributed through the batter so it releases gas throughout, giving an even rise. Uneven mixing leads to pockets of uneven lift and texture.

Swap the raspberry

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

  1. Raisinfits better

  3. Figfits better
  4. Raspberrythe original

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