Why it works: Flour and rhubarb match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 670 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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
- All-purpose flour
- Forms the structure of the paste that holds the pudding together.
- Baking powder
- Releases gas during steaming so the pudding rises and becomes light.
- Butter
- Cut into the flour to add richness and tenderness to the paste.
- Lard
- Adds fat that keeps the paste short and tender in texture.
- Fruit
- Provides moisture and flavor inside the pudding.
The step that matters
Cutting in the butter and lard. Fat should stay in small, coarse pieces rather than fully blending into the flour. As the pudding steams, these pieces melt and leave pockets that keep the paste tender instead of tough and dense.
Swap the rhubarb
How well each one fits the dish's main ingredients (flour, butter, sugar):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits better
- Rhubarbthe original
Fit is the average pairing score against flour, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
