Why it works: Bread and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 11,466 recipes. Both carry 2-undecenal, which smells sweet. The science ↓

Ingredients
Directions
Make the batter
In a bowl, mix the suet, bread crumbs, flour, sugar, salt, and baking soda.
Beat the egg and mix it with the milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Suet
- Adds richness and a tender, moist crumb as it melts during cooking.
- Flour
- Provides the structure that holds the pudding together.
- Baking soda
- Reacts with the vinegar and gives the pudding lift.
- Egg
- Binds the mixture and helps it set firm.
- Milk
- Moistens the dry ingredients into a batter.
- Vinegar
- Reacts with the baking soda to produce gas that aerates the pudding.
The step that matters
Stir in the vinegar last. Vinegar reacts with baking soda right away, releasing gas. Adding it at the end and moving the batter straight into the mold keeps that gas trapped so the pudding rises rather than going flat.
Swap the ginger
How well each one fits the dish's main ingredients (bread, flour, sugar, egg, milk, vinegar):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Gingerthe original
Fit is the average pairing score against bread, flour, sugar, egg, milk, vinegar. Candidates are from the same food group and used in at least 100 recipes.
