Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the main body and tart flavour of the pudding.
- Brown sugar
- Sweetens the rhubarb and adds a deeper, caramel-like flavour.
- Arrowroot
- Thickens the cooked rhubarb into a smooth, glossy pudding as it sets.
The step that matters
Stirring the moistened arrowroot into the boiling rhubarb. Arrowroot must be fully dispersed in cold water first, then added to boiling liquid, so it thickens evenly without lumps. Adding it dry or to cool fruit can leave clumps or a weak set.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, arrowroot, milk):
- Cinnamonfits better
- Rhubarbthe original
- Nutmegfits less well
- Turmericfits less well
Fit is the average pairing score against sugar, arrowroot, milk. Candidates are from the same food group and used in at least 100 recipes.
