Why it works: Rice and flour are a kitchen classic. They rank in the top 10% of all ingredient pairs, and 6,079 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe

What each ingredient does
- Rice flour
- Its starch thickens as it boils, forming the gel that gives the jelly its body.
- Loaf sugar
- Adds sweetness and helps the starch-based mixture set into a firmer, clearer jelly.
The step that matters
Boiling the rice flour mixture. Rice flour starch must be heated while stirred so it gelatinizes evenly; if it sits still, lumps and scorching form and the jelly sets unevenly.
