Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Tapioca Jelly
Ingredients
Directions
Prepare the tapioca
Soak the tapioca in cold water for 4 hours.
Set a saucepan of boiling water on the stove.
Add more lukewarm water to the tapioca if it has absorbed too much liquid, stirring frequently.
If the mixture is too thick after it begins to clear, add a small amount of boiling water.
Cook and set
Once the tapioca is clear, stir in the sugar and lemon juice.
Pour the mixture into molds and refrigerate until set.
Serve
Serve cold with cream and flavor with rose water if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tapioca
- Its starch thickens as it cooks and sets into a clear, tender jelly when chilled.
- Lemon juice
- Adds acidity that brightens the sweetness and balances the flavor of the jelly.
- Sugar
- Adds sweetness and balances the lemon's tartness.
The step that matters
Adding water to the tapioca as it cooks. Tapioca starch absorbs liquid and thickens as it heats, so the mixture can become too thick or stiff. Adding lukewarm or boiling water loosens it, keeping the jelly smooth and pourable before it sets.
