Why it works: Sugar and condensed milk work together. They rank in the top 11% of all ingredient pairs, and cooks put them together in 804 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Its starch breaks down in the boiling water, thickening it into a soft, smooth gruel.
- Sugar
- Adds sweetness to the finished gruel.
- Condensed milk
- Adds sweetness and creaminess when used to flavor the gruel.
The step that matters
Boil the rice until it almost dissolves. Rice starch only thickens the liquid once the grains have broken down. If the rice is undercooked, the grains stay firm and the gruel turns out thin and grainy rather than smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
